"my doctors keep pushing this drug on me. doesn&#039;t do a thing. i have osteoarthritis in my left knee after being assigned to usmc units for a number of years as a navy corpsman. carrying over 80 lbs of gear on your back not including weapon, flak and kevlar. doin multiple humps and running like the wind has taken it&#039;s toll. but this drug does not work for me. the only thing it does is make me tired."
