Phentermine
"I'm the same user from 3/18 post, I started on 1/7/11 at 332.6lbs. I took 30mg for 60 days. I got another script for 60 days from my doctor. I changed all my eating habits from the first day and started to exercise. I decided to take a break for 10 days to get it out of my system before starting the new script. I noticed no side effects of stopping. I stuck with the diet and upped the exercise just a little. I still lost 3lbs that week! The week before, still on pills, I only lost 1.8lbs. I decided to stop taking it all together. I'm down to 295lbs. You must change your diet and exercise."
