I did when I took it...I found I needed more food haha.

Actually, I have stopped taking it because I couldn't work out like I wanted. I was so sick and weak after a workout, it was pretty scary. I have stopped taking it and upped my calories to 1600-1700 and I feel like I am back to normal, and hitting the gym hard again. I am not sure why I thought 1200 calories when I work out 5 days a week was a good idea lol.

Saying that, I still think Phentermine is a good jump start. If you have hit a plateau, I would recomment not taking it for a week and upping your calories.
