I took phentermine about 3yrs ago and lost about 30lbs. I am now 21yrs old and have gained back the 30lbs, plus an additional 10lbs. I am about 5'2" and am very uncomfortable with this extra weight, especially now that it is summer! I am just unsure what to do to keep the weight off for good, and not sure if I want to take this drug again. I didn't like how it made me feel. I want to hear about other people's experience with this drug and learn how to keep the weight off for good!
