"i am now on my second round of phentermine. my first 3 months however were amazing! i&#039;m so excited to see how the next 3 months go. i have lost over 45 pounds in 3 months on phentermine. i went from a size 22 in pants to a size 16. i can go more than just a few feet without losing my breath. i was in a hopeless situation with my body, i couldn&#039;t run, i couldn&#039;t breathe.. i could barely walk without losing my breath and energy. now i&#039;m 236 lbs and i&#039;m ready for round two! people say once you stop the medication you gain it all back. but my lowest was 232 and i&#039;ve only gained 4 lbs in 3 months. (i was on 3 months, off 3 months) if you drink your water like you&#039;re supposed to, don&#039;t splurge on your calories or carbs, you will lose the weight!"
