"i&#039;ve been taking phentermine for 1 week and i&#039;ve lost 15lbs. day 1, i weighed in at 271lbs and exactly 2 week later 256lbs. i&#039;ve weighed in almost everyday because after the first day i&#039;d lost 5lbs and i couldn&#039;t believe it. i feel nauseous a lot and don&#039;t desire any food but overall i&#039;m having a good experience."
