"about 3 yrs ago, i was 70 lbs overweight.  i decided, what the heck, let me try phentermine.  i only took 1/2 pill per day.  first week i felt the side effects like a little shaky, etc.  i just kept taking 1/2 pill per day. i did not change my eating habits, the drug did that for me.  the weight started just falling off. i lost 50 lbs in 3 months and eventually got down to my goal of 70lbs.  i haven&#039;t taken it in 2 yrs and have slowly crept back up, about 20 lbs and still have about 30 pills left."
