"i started off at 277 lbs 8/20/2014.  my doctor prescribed 37.5 mg 5 days on, 2 days off so i could stay on it for a longer period of time without building a tolerance.  i cut the pill in 1/2 and followed the 5 days on, 2 days off for 6 months before having to take the whole pill 5 days on, 2 days off.  because dr had prescribed the full amount and i only took 1/2 it doubled my medicine but i picked up my monthly prescription so i&#039;d have extra when needed.  dr. cut me off at 7 months even though i was still loosing so i was glad i had saved extra to continue.  few dr.s warn about tolerance, 5/2 works so that doesn&#039;t happen.  i weigh 203 after 1 year, going back for another prescription soon.  do your part, eat right, it works."
