"this is my second review, last time i commented i was at 205 lbs and 11 lbs lost in two weeks.  at third weigh in on 2/22/14 i lost another 4 lbs and now weight 201lbs.  i went from 216 to 201 in 3 weeks.  i would say yes, phentermine definitely works to curb my appetite.  my next weigh in is march 1, 2014.  i hope to be under 200 (fingers crossed).  i don&#039;t want to get my hopes up since i&#039;ve already lost &quot;a lot&quot; for the first month according to my doc."
