Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I have been on Adipex for two weeks. My doctor suggested it to help me lose some weight. I was 200 pounds at the start. I am now 194 lbs after 2 weeks. I take a half pill a day. I work at a desk all day and would have issues with snacking all afternoon. Now I don't. I force myself to eat some fruit every afternoon or a protein shake. I can't eat a full meal because I feel fuller faster. I have more energy. I have had dry mouth, but drinking water is a big help with that, and I drink a lot more water. I do have some heart racing at times, but the more water I drink, the better that is, which is good because it did throw me into a few panic attacks. No headaches. I did get insomnia the first two nights, but I switched to taking the pill at 10 am instead of noon and that stopped. I started exercising so hope to see more weight drop off. My goal weight is 145, but I am only taking this until my bottle is gone."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I am 44 years old and I was 182 pounds 3 months ago. I started diet by myself and I was able to lose 10 pounds. I went down to 172. Then I got stuck. I finally went to my doctor and he prescribed me the Adipex pill. I started last Thursday at 172.5 pounds, exactly 6 days later I am down to 166.6, and it's not even a week yet. I will keep you posted. As for side effects, only the first 2 days I had a light headache, but I am okay now; I am very thirsty. I started walking every day for at least 35 minutes. I still have a problem with my foot, so I go very slowly, but I am trying. So far, I love it. I am not hungry, and I am very careful about what I eat. I eat vegetables, fruits, lots of water, and fish. Sometimes a small piece of grilled chicken. I forget to eat, but I am trying to eat in between veggies or fruits because I don't want to gain all the pounds back once I stop the medication. I will take it for 3 months, so I still have a long way to go. I need to go down to 130; 36.6 pounds to lose."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I started taking Adipex on July 15, and I must say I have definitely seen a difference in my eating habits and it's only been 3 days! Amazing! I was 127 lbs in 2012 and somewhere along the line I lost the will to work out and stay fit. Needless to say, I gained about 35 lbs since then. So, I am giving Adipex a try, and it's doing wonders for my appetite! I experienced dry mouth the first day, and that's the only side effect I have had. I eat yogurt for lunch, and dinner is 2 turkey sandwiches on wheat bread, and I drink 2-3 bottles of water a day. Eating right and exercise are key to helping drop weight quicker! Once you stop taking the pill, you must maintain good eating habits along with exercise, or the weight will come back plus more!"

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I've been taking Adipex capsules for 1 week now and I am down 11 pounds. I don't exercise. The pill just makes me not want to eat. I have to make myself eat. I also have severe dry mouth, so I drink water way more now. The only other side effect I have is heart flutters. But I can handle that, because it happened to me before I was on Adipex."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I just started taking Adipex. I think so far it's helping me a ton. I'm on a 1000-calorie diet plus Adipex. I'm working out every day. This is my 5th day, and I already lost 6 pounds. Adipex seems to be helping me from overeating; it seems to be helping me curb my cravings. I have no craving for sweets of any kind, so far so good."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I am 20 years old and I have always had problems with weight loss since I was in middle school. I went to the doctor and was prescribed Adipex. I have been on a low-carb diet, and I have been on Adipex for 9 days now, and have lost 6 pounds so far. I am very happy with the results right now and I'm hoping to keep at it and try to reach my goal weight! I am 5'4, and before I started the diet, I weighed in at 192 lbs, and so far I am down to 186 lbs. My goal weight is 145 to 150 lbs!"

For Weight Loss (Obesity/Overweight) "While this medication may seem useful & effective in the beginning, be careful. I've been taking this medication off & on for approximately 10 years. I've found the longer I'm on the medication, the more addicted (mentally & physically) I am to it. I love the energetic, invincible feeling that it gives me in the beginning; however, I've found that I am more irritable & moody now too. I have gotten to the point where I feel I can't function without it, although it's lost its suppressant effect."

I’m 5ft 8 and weighed 240 lbs. I went on a 1200 calorie diet for 3 months and loss 10 lbs. I leveled out. Went to see my PCP for some help. He put me on Phentermine 30mgs per day .

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I started taking Adipex in Sept and went in on Dec 7th for my three-month check-in, and I lost 38 pounds. I am 5'8'' and began weighing in at 259, and now I'm down to 221, and this is without including exercise. Walking is part of my daily routine; I walk a lot throughout the day as I'm running between classes and then to go to work. I did experience some side effects the first week, like being lightheaded, dizziness, and a dry mouth. But I use that to increase my water intake. My doctor actually recommended I only take it about 5 days a week so that my body doesn't become so used to it, and that's what I have been doing. So far, so good, and I can't wait to continue losing weight."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "Teva changed adipex formula (no blue dots anymore) and although they say that was the only change, these are worthless. Not only did the cost go up, but they are ineffective. I spent $600 for 90 supply!!! I have to take 3 whole pills to get any effect whereas the pills with blue dots 1 to 1.5 was sufficient. All it does is make my face super hot and makes me super tired. I have called and reported it to teva also, but nothing is being done. Not ok to do this to consumers and take advantage like this."

Fastin (phentermine) for Weight Loss (Obesity/Overweight) "I just started using Fastin and I like it better than other diet pills I've tried, such as Hydroxycut, because it doesn't make me feel sick or nauseous. However, it definitely makes my heart rate skyrocket, so for the first couple of days, I would only take half a pill at a time. A full pill makes my hands tremble, and I can hear my pulse in my brain."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "It hasn’t been a month yet. I started Adipex-P, one tablet daily. I never believed there is such a pill to help me lose weight because I was tired of everything I tried and nothing worked out. Until I started this miracle pill, as I said within 3 weeks, I went down from 190 lbs to 169 lbs, unbelievable! I'm so happy with my results. My goal is to go down to 155 lbs or around. I’m 5’6”."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "This drug is extremely effective. If you're not losing a lot of weight very fast like the more amazing stories you read, you are not taking full advantage of it. It will give you an amazing kick start to a new life that will be very difficult to maintain, and that you must be very committed to, or you need not bother -- because the weight will come back otherwise. Friends & I lost 20 lbs per month, so 6 months is the max length of time you should be using it. After you are finished with it, the real you will reappear, and you will again have to fight all your original demons: hunger pangs, portion control, willpower, laziness. If you can't do that, don't bother to set yourself up for yet another diet failure and heartbreak. OK 2B Hungry :)"

Fastin (phentermine) for Weight Loss (Obesity/Overweight) "I’ve been taking Fastin for about a year. And took it for a few months the year before. I love this medication. It helps me not be so tired. I take it as soon as I wake up, and I’m good for the rest of the day. When first taking it, make sure you eat a little something; otherwise, it will make you feel sick. It does make your heart rate go up. I don’t mind it because I know you have to get your heart pumping to lose weight. Went from a large 16-17 to an 11-12. 205 lbs to 160 lbs in the past year, and I’m only 5 ft 2 in. (I have large hips). It helps me have energy that I haven’t had since I was a teenager. And I only take one tablet in the morning. This medication is a blessing to me!"

For Weight Loss (Obesity/Overweight) "I started phentermine right before Thanksgiving. I am 5'2'' and starting weight was 184 lbs. It made me not hungry at all. I constantly drank water and ate very lightly. No insomnia first month. I lost 17 pounds. Second month I had to take 3 days off because of the insomnia. If I feel I can't sleep, I will skip a day or two. Still only drinking water and eating lightly. No exercise at all, and today I weigh 156 lbs. Total loss of 28 lbs in two months. This month I plan to add exercise to drop more weight. Love Phentermine!"

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I was on Adipex in 2010. I started out at 272 lbs. I was amazed at how much weight I lost every week. I had to buy new pants, jeans, etc. every week. I averaged 8-12 lbs lost per week. I lost 126 lbs in just under 5 months. I was very active, exercised every day, and didn't have the craving for food. I did find that not eating led to headaches and mood changes. You have to eat!"

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I was put back on Wellbutrin back in February '09, and I started at 223 lbs. A month later, I went back for a checkup and lost 6 lbs on my own. I then asked about Adipex. The doctor put me on it in March '09. I lost 19 lbs the first month. It is now August '09, and I am down to 159 lbs - below my goal weight of 165 lbs! This is the last month I will be taking Adipex, but I will continue my low-carb, no sugar diet. I also exercise 2-3 times a week at the gym for about 75 minutes. It has really helped me change my lifestyle. There is no magic pill out there! You really have to be dedicated and willing to work hard."

For Weight Loss (Obesity/Overweight) "Hello. I'm a 28-year-old female standing 5'3''. I went to my doctor on 7/31/14 and was prescribed phentermine 37.5. At the office, I weighed in at 275 lbs.! I started taking the medication on 8/1/14 (half a pill to see how it would affect my heart rate. I have hypertension). On 8/2/14, I weighed myself, and the scale read 269.6. I only took half a pill that day, too. This morning, 8/3/14, I weighed in at 265 on the nose! I've been overweight since the age of three and remember being on diet pills at the age of nine. I've tried it all. As an emotional eater who needed a miracle, all I can say is thank God."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I was prescribed Adipex on Nov 10, 2014. I weighed 155 pounds. To some that might not seem like a lot, but it was to me. I had tried working out and eating right, and nothing was helping. Today, Dec 22, I weighed 135. I have steadily lost weight since starting it. I skip some days and still feel energetic and not as hungry. The first week on Adipex, I had the worst dry mouth. I couldn't drink enough water. I'm still pretty thirsty, but it's manageable. Drinking water helps the medicine work better. I have also changed my eating habits to use when the pills are up. The first night I didn't sleep, but now I can go to bed no problem. This medication isn't a quick fix; it simply is helping you make lifestyle changes to keep weight off."

Adipex-P (phentermine) for Weight Loss (Obesity/Overweight) "I restarted Adipex today. Full dose. I had amazing results 2 years ago. Went off it, but gained 40 lbs back. Unlike some user reviews, I can tell you the weight gain was NOT a result of quitting Adipex. It was poor choices in diet and lack of exercise. I got lazy. But NOT because I quit taking Adipex. I started today because I need help. It is a potent drug. And it will make you not want to eat. EAT ANYWAY. When you don't, you WILL experience mood swings and hostility. The purpose of this drug is to HELP you make better food choices and to get into a good exercise routine. Drink LOTS of water and EAT every three hours. Do some research BEFORE taking this drug. It can be EXTREMELY beneficial if you use it the right way. Good luck all."

For Weight Loss (Obesity/Overweight) "I started taking 37.5 mg at the end of June 2023 and it's now the end of December 2023. I have lost a total of 53 pounds in 6 months. I have cut out carbs, sugar, and stuck to water (trying not to drink my calories), all while staying in a calorie deficit. I also have not worked out one day this whole time. Don't get me wrong, I am human and have my days where I have a cheat meal or a piece of candy, but I definitely limit myself to this. Overall, I highly recommend this medication as a way to help you change your lifestyle. Take this as early in the morning as possible as it gives you a lot of energy and taking too much may keep you up at night. I have experienced dry mouth with it, but it has gotten better the longer I take it. On the plus side, the dry mouth makes you drink more water and chewing gum helps. I would say to give this medication a fair two-month trial to see if it's a good option for you."
