For Weight Loss (Obesity/Overweight) "I have been on the 35 mg, 2x a day for 2 days, and I have no appetite at all. I am very focused, have tons of energy, and feel amazing. I have a heart issue that my doctor is aware of, and this dosage does not make me feel jittery at all. I don’t even know what my starting weight was as I was too embarrassed to look at the scale, but feel I need to lose close to 50 lbs. Only negative...not tired!!!"

Phendimetrazine for Weight Loss (Obesity/Overweight) "I have been on Bontril since December 28th, 2010. I am pleased to say that I have lost 7 pounds the first week and 6 pounds the second week, and tomorrow will be 3 weeks and I have lost 3 this week. In total, I have lost 16 pounds so far. I have experienced dry mouth, suppressed appetite, and headaches. However, none of them bad enough to make me stop yet. When I look in the mirror, I am so pleased. I started out at 171 pounds and now am at 155 pounds. Every day I am excited to see what my scale says once I get up. I would recommend this to anyone that needs to lose weight. LOTS of WATER will make you feel full, so it is very much needed. I haven't been able to exercise yet due to an injury in my back."

Phendimetrazine for Weight Loss (Obesity/Overweight) "I started Bontril on 6/17/13. The first week, I lost 10 lbs. I eat cleanly and exercise 3 days a week. Side effects include insomnia only if I don't exercise, decreased appetite, increased energy, a slight headache. I haven't lost any additional pounds."

For Weight Loss (Obesity/Overweight) "I started using Phendimetrazine 35 mg about 8 weeks ago. I lost 20 lbs. I was amazed at the results, but I also take additional supplements and vitamins too. I'm being seen by 2 doctors. One takes care of my general health, the other, weight management. I started out at 190 lbs, and now I'm at 170 and counting. I recently started taking the 105 mg. I'm not used to it yet. It really suppressed my appetite. If I didn't think to eat, I wouldn't have. I must keep my metabolism active. What I don't like about it is it keeps me awake, and I don't get good sleep at night. I was told to take the 105 mg and then the 35 mg at dinnertime if needed. If you have a hunger issue, 105 mg is the one for you. It's serious, but please eat a little. It works though."

For Weight Loss (Obesity/Overweight) "I first tried Bontril about 7 years ago when I went to a weight loss center. I lost 47 pounds and kept it off for about three years. I remember taking two pills 30 minutes before each meal, 354 mg tabs, and I was told not to take my last dose after 4 PM due to it will keep you from sleeping. I also followed a high-protein diet. I was like 190 pounds then, and I think I got down to 147. But over the years, I've gained weight, had a baby and gained more weight. I'm now 235 pounds and started taking Bontril a week ago, and I've lost 4 pounds in a week. I was told to take 1 pill an hour before meals, I've increased to 2 pills before breakfast, 2 before lunch, and 1 in the evening, and I have no appetite. I have to make myself eat. I hope this continues."

For Weight Loss (Obesity/Overweight) "Started taking phendimetrazine last Tuesday, opted to be part of a study that a friend of mine told me about. I'm 5'9, 144 lbs - by no means overweight. Yet, I was trying to shed just 10-15 lbs to get back down to the weight I once loved and felt my best at. 2 a day, an hour before meals. First day it suppressed my appetite, and I was more than a little surprised - thought I hit the jackpot, as I am the queen of snacking throughout the day. 2nd and 3rd day didn't work as well as the first, 4th and 5th day worked good again. Now I'm on my 7th day, and today it hardly worked. Not sure what all the back and forth is about because I haven't done anything different. I will say that I've dropped 4 lbs in the past week, but I'm also taking water pills."

For Weight Loss (Obesity/Overweight) "DO NOT USE THIS MEDICATION!!! A friend of mine used this medicine and turned into a different person. She went from a kind role model to so many people, to someone we barely see. When we do see her, she seems irritated and is very harsh. She has received so many side effects such as... • Mood changes • Increase of sexual desire • Loss of appetite • Loss of interest in certain priorities."
