Thats a tricky problem.
Alcohol is probably the bet solution as irresponsibel as it sounds!

My fear is needles, and when i have to get any medicine i have to do somethin to take my mind off it, like putting a stone in my shoe but refusing to take it out, better discomfort than blind fear!

My gym is pretty famed for producing power punchers, i don't no why, thats why sparring is pretty technical and rarely gets heated, mind you when it does, the whole gym turns and watches!
