Phentermine
"I started on 8/8/15 at 257lbs, tomorrow will be 2 weeks I have been on it and I'm down to 240lbs, that's down 17lbs!! I work out 4 to 5 times a week,  walking 3 miles or the elliptical for 45 mins. I have cut out all sweets as I noticed foods with a lot of sugar make me shaking while one the pills. I have like no appetite, but make myself eat at least 3 times a day,  I mostly eat fruits and veggies when I do eat. I drink about 8 bottles of water a day due to dry mouth and excessive sweating when working out.   I have only found 2 side effects dry mouth and constipation which I take a stool softener every morning to help with."
