"today marks 4 weeks since i&#039;ve been on phendimetrazine. i&#039;ve since lost 14 pounds as of this morning. little to none exercise. i have cut back my eating because i dont tend to think about eating 24/7. i definitely need to eat better and exercise. probably would get better results. the only real side affects i have is not sleeping well. i usually get 6 hours of sleep a night and up the rest of the time. all in all i&#039;ve had a good experience. also: i was 331lbs when i went to the doctor august 25th. i&#039;m 227lbs today september 22nd. good luck everyone."
