"i started taking phentermine after going last september to a weight loss doctor who informed me that i had a pre-diabetic body shape. that&#039;s pretty incentivising to lose weight. i had already decided that i just had to lose weight. i also decided that i had to make more significant changes to the way i eat. i take half a 37.5 mg pill once a day in the morning. i have lost about 42 pounds since i started taking phentermine. that period included about three months at a plateau. the first month i lost 30 pounds. more recently i have added another 12 pounds to my weight loss. phentermine has certainly curbed my appetite, and it has been terrific in helping me change my approach to food."
