"i took adipex for 6 months... my starting weight was 210.0 ... ending weight was 165.0 ... that was a year ago.  this is my advice. #1. you may not feel like eating... but do it anyways... or you&#039;ll slow your metabolism down to a crawl and stop losing weight. just watch what you eat!!  #2. take vitamins!!!! by the time i hit 165# - my hair was starting to fall out, i couldn&#039;t focus, and i was constantly tired - sometimes i&#039;d nearly pass out... because &quot;i didn&#039;t feel hungry&quot; and just wasn&#039;t really eating more than 500 calories a day.  even sitting still your body burns way more than that! #3.  be prepared to gain some of that back when you come off the pill.  i wasn&#039;t prepared at all - and i gained it all right back.  still, great pill!"
