To me the worst part of this story is that you couldn't stay awake during the tournament, but once you messed up and lost, I'm pretty sure you find it very hard to get sleepy with all the anger you were feeling.

I've also been sleepy in tournaments and messed them up because of that (not like you did though ) so I know the feeling. I always tell myself, why the f... couldn't I feel as awake as I am now (angry at myself after losing in a stupid way) during the tournament?
