"in december 2013 i hit the 300 lbs mark after slowly gaining weight for many years.  i have tried many diets including variants of the low carbs.  in december i went to the doctors for an appetite supressent and went on qsymia.  i enrolled in a manufactures program which gave the first two weeks of meds for free then i paid $75/ month for 3 months.  after 3 month, the price of qsymia went up to $150/mnth (best case with coupon), so my doctor gave me a prescription of phentermine  and another of topiramate (cost 35/month total as my insurance covers the later). in 6 months i lost 60 lbs!  in the last 1.5 months i lost only 5 lbs, but my doctor explained that i should go off the meds for a few months and then the meds will be effective again."
