For Weight Loss (Obesity/Overweight) "Previous user of Adipex (phentermine), which would work great for the first few weeks, but then totally wear off, not to mention the side effects (insomnia, heart palpitations, constipation, anxiety) were annoying to deal with. Switched to Bontril and am so happy I did. I feel calm and focused. It's the oddest thing to not have to 'stress' over counting calories and choosing good food options. It just sort of is a perk with Bontril. One tip: drink lots of water. Bontril, water and clean eating dropped 8.7 pounds off me in a week. One of the best parts is going to bed and being able to sleep, which was hard with Adipex."

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 have been on Bontril 105 for two weeks today and have already lost 10.3 lbs. I also exercise 45 plus minutes every day and follow the food pamphlet the doctor gave me. I do have a free day on Sunday, though. I have not had any bad side effects or sleeping problems except the first two nights. I am planning to lose at least 40 more lbs and then get off the pills and continue exercising to help me keep it off."

For Weight Loss (Obesity/Overweight) "I started taking Bontril about 5 days ago and have already lost 11 pounds. Amazing! I am not at all hungry, I have to make myself eat 3 meals a day, and the only thing so far is I haven't slept well. Hopefully this will subside. I started at 166 pounds, and I am 5'6" tall, and my goal is 145 pounds."

For Weight Loss (Obesity/Overweight) "I've been taking Bontril SR (105 mg) for 30 days. The 1st week I lost 7 lbs and the 2nd week I lost 3 lbs and none since. The 1st week I had tons of energy and a significant decrease in appetite. The 2nd week my appetite started to come back and the energy was gone. I now have almost the same appetite as before, although I do get full a little quicker. Went to the doctor today to get a refill. Going to try 1 more month. I did follow the 1200 calorie diet and drank lots of water the 1st 2 weeks. It is hard to restrict calories now that the hunger is back. As far as side effects, I did experience headaches, insomnia, and dry mouth for a few days, but that has gone away. I was also irritable that 1st week. Now the only side effect is dizziness if I don't drink enough water."

For Weight Loss (Obesity/Overweight) "My Dr. prescribed Bontril one week ago and have lost 5 pounds. The only side effect was insomnia for 2 days. I usually walk 15-20 mins and when I eat I get full really fast, this is what I needed."
