"my experience with phentermine has been wonderful. within the first 3 days of taking it, i lost 7 pounds. i haven&#039;t even been on it two weeks yet and i&#039;m down another 7 pounds. i also watch what i eat, when i eat all the time. calorie count everything and exercise everyday for 30 minutes to 1 hour. plus i am positively more active, increased sex drive and simply happy. i am scattered brain and dry mouth. i suggest lots of water and green tea.
