"ok, this is actually my 2nd time taking phentermine. i took it 3 yrs ago and lost approximately 32lbs in 3 mths but however i thought i did a good job trying to maintain my eating habits. after 3yrs off of phen i slowly gained 20 lbs. i&#039;m here to say that phen is a terrific  jump start to help you learn healthy eating habits. however after using phen the weight will in deed creep back on you....so here today i have been on phen for almost 3 weeks my starting weight was 170.0.... i am now at 156....so about 15lbs off in 3 weeks!!!!! so this time around i&#039;m going to appreciate the phen jump start to weight-loss, and maintain a healthier lifestyle this time around. phen does the work at , but it&#039;s up to you to maintain your healthier lifestyle"
