obesity
"I took phentermine and counted carbs, exercised, lost about 30 lbs, but after 5 or six months, no changes. Dr said stop. My weight had been creeping back up About a year later (or more) & I decided to try finishing the bottle, it was expiring. 37.5 mg, x 38 days, lost another 4-5 lbs. It has taken me  4 weeks to get reapproved from insurance. Had anyone else had success after stopping when it no longer works then starting again?"
