"this is my second time on phentermine. i took it about 14 years ago, at age 26. i was 280 and i lost 94lbs in 4.5 months. but, i only ate protein and vegetables and i walked/jogged at least one mile each day in addition to 45 mins of floor aerobics, 45 mins of step aerobics, and 30 mins of weight training exercises. i recently had reconstructive surgery on my ankle and i gained 60 lbs since august 2014. my exercise is extremely limited at this time. i am starting at 280 lbs. i will update soon."
