Phendimetrazine 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."

Phendimetrazine 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) "Please read my entire review, as I feel it is beneficial to anyone using or considering this medicine. I am a 30-year-old male, and 6 weeks ago, I weighed 204 lbs. I have taken phendimetrazine 35 mg 3 times a day for 6 weeks now. I have dropped almost 40 lbs and look and feel the best ever. I exercise 30 minutes a day-nothing major, just a light jog. I eat 4 small meals which are: soy products (Boca burgers, veggie dogs, etc.), eggs, fish, seafood, dark veggies, and cheese strings. (Eating meat will cause MAJOR constipation.) I don't drink alcohol or soda. It's really easy."

Phendimetrazine 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."

For Weight Loss (Obesity/Overweight) "In 2008, I took phendimetrazine, and along with diet and moderate exercise, I lost 40 lbs in 3.5 months. The only side effect I had was occasional constipation when I didn't drink enough water. I didn't feel 'the energy boost' like I was told I would. I loved it then! After gaining back 15 lb (gained weight with pregnancy) and realizing my baby is now close to 3, it's time to get back into gear. Tried diet and exercise by itself with minimal results, so I resorted to finding a weight loss clinic. I've been on the extended release for 5 days, and it seems to be different. It doesn't seem to suppress my hunger like the first time around. I am still taking it though, I will weigh in on Oct. 16, so hopefully I will see results!"

Phendimetrazine for Weight Loss (Obesity/Overweight) "I have been using Bontril for 7.5 weeks with only a 6 lb weight loss following a great diet of protein, fruits, and vegetables. I just phoned my physician's office and informed them that I plan on taking myself off of the medication secondary to severe constipation, headaches, insomnia, fatigue, and frequent urination. I have been off the medication for 5 days and feel so much better. I didn't realize the potential cardiac complications until today. Oh well, live and learn! Good luck to all!!"

For Weight Loss (Obesity/Overweight) "I have been taking Bontril for 3 months and have lost over 17 pounds, which is only 3 pounds from my goal. The only side effects I have felt are some constipation and a slight increase in headaches. I'm starting to wean myself off the pills now and have found no increase in my appetite. This medication worked great for me!"
