obesity
"I have lost 35 lbs. so far on phentermine. I have a lot of energy, but the trade-off for me is lack of a good nights sleep. I also have noticed that, unless I have been off of it for at least four weeks after being on it for five weeks I don't lose weight and my appetite is not under control. My doctor does this so that I don't become dependent and require more to lose weight. I am trying to get more exercise, but I am not good at getting out there as much as I should. Also, I need to control my carbs better. That, along with the exercise is key for me. Good luck to all of you trying to lose weight. "
