For Weight Loss (Obesity/Overweight) "When I was 33, I weighed 185 lbs. At only 5'3", I was extremely overweight. I had never had a weight problem before, My average weight was between 125 and 130. After four months of staying home and not going out at all, I put on weight fast! I started taking Bontril and changed everything: Didn't eat after 6, stopped drinking soda, avoided fried foods, no fast food, used smaller plates for smaller portions, and drank lots of water. In three months, I got down to 122 lbs. I loved it! I tried it a second time in 2012 with no results. It was a stressful time for me. I am now trying it again and have lost 12 lbs in 2 weeks. It's a great product for weight loss! The only side effect I ever experienced was mild constipation when I didn't drink enough water."

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) "42-year-old, 5’6” female. Started at 181 lb on March 19th and down to 159 lb on June 12th. Only took one tablet a day. Taking more than that, and I had zero appetite. Caused severe constipation, so drink plenty of water and eat lots of fiber. Very effective drug without making me jittery. Recommend for anyone who needs some help. I hope to be down to 140 in the next 4-6 months."
