Phentermine
"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't want to get my hopes up since I've already lost "a lot" for the first month according to my Doc."
