"i started taking adipex-p 37.5mg on april 1, 2009 and my starting weight was 210lbs. i went back after one month and lost 17lbs. i went back to my doctor on july 30, 2009 and i weighed 168.5lbs which is a result of losing 41 1/2lbs! i am super excited and can&#039;t wait to lose more or at least to get to my goal of at least 135 to 140. the only one complaint i would have about it is the energy level totally disappears after your first or second week."
