curse you guitar hero!

Last night, at a new year's/ college farewell party, I played guitar hero against my friend, and now I can't type for too long. basically, I beat him on "through the fire and the flames" (dragonforce) by getting a 70%... on expert mode... somehow, and afterwards, my wrist and two middle fingers reached the state of total muscle fatigue. I have limited typing ability now, so my first issue is going to be a bit delayed.
