"this medicine work. i was on phentermine 37.5mg for three months, during that time i was starting to really lose the weight starting at 290 and ended up at 262 at the end of three months. trouble is due to the laws of ohio i am limited to just three months. i know if i had been allowed to continue i would have lost far more. i have a bad back - three operations, both knees are bone on bone. my left arm has painful arthritis, so exercise is very painful if not impossible for me. i do not over eat, do not eat sweets, do not drink sodas. i &quot;need&quot; this to increase my metabolism, i do not over eat. i am now back on it."
