Guys I need your opinion on this. I'm a 19 year old competitive hockey player, 6'1", 190lbs, and I take 2 ephedrine pills an hour before games. I started using it last January until March then stopped and then re-started this past September and have been continuing to use it. I only take before games which is twice per week and have not experienced any serious side effects besides the sweating and odd muscle spasm. I am perfectly healthy and don't see any reasons to stop taking them. I just want to know what you guys think. Should I stop?? Thanks guys....
