"i was on phentermine several years ago but didn&#039;t really try to change my eating habits and so it didn&#039;t work. i decided to try it again because i just keep piling on the weight and am slowly killing myself. i&#039;ve been on it 3 days now and have already lost 8.4 pounds! i know it&#039;s mostly water weight right now but seeing that scale move so quickly is such a big motivator. my starting weight was 443.8 and now i&#039;m 435.4. i eat between 1200-2000 calories per day. i&#039;ve noticed that i&#039;m eating less each day though and it helps take away the cravings so i can make smart decisions about what to eat. i am also watching my carbs and sugar intake. only side effect i&#039;ve had is mild dry mouth and not feeling sleepy during the day like i normally do."
