"i went to a very expensive weight loss clinic.  i followed a strict eating plan while i took the medicine.  i&#039;m over 50 and nothing has worked for me for the last 8 years.  it was because of the adipex.  i lost 25 lbs in 12 weeks.  i have been maintaining for 5 weeks now.  i still follow the strict eating plan, but not being on the medicine, i&#039;m not losing weight.  i wanted to make sure i could maintain the loss.  i&#039;m going to my pcp later this month and am going to do another round and lose the final 10-15 lbs that i need to lose. this medicine just &quot;shuts your mouth&quot;, that&#039;s the best way to describe it.  it does give you energy, it focuses your mind.  i was worried about how i would feel after stopping, i weaned for about 5 days with a half pill."
