"i&#039;ve been on phentermine since sep 2, 09. i was 291lbs. today, still taking it, i&#039;m 248lbs.that&#039;s a loss of 43lbs &amp; there are no words. for about 6 weeks i didn&#039;t take the drug because of certain reasons. coupled with exercise, running 1.5 miles 3-4 times &amp; doing zumba 4-5 times a week &amp; watching what i eat. i see the results &amp; i&#039;m very proud. i&#039;ve found that phentermine is not meant as a simple, quick fix, but is to help change your body and mind so that you can maintain because a change of mind has taken place once you are off. i suggest exercising when you start taking it because the weight will come off even if you do nothing, and that can be deceiving in that you won&#039;t think you have to work as hard and you&#039;ll gain it back plus some when you stop."
