Ugh so tired

Two nights ago I was up until 4am playing the new Crysis demo. Last night I was up until 4am because I had gone to a party to play halo. Three of the people there were the kind that do nothing but play halo and nothing else, and they wouldn't split up their team. They won every single game, even when it was 4vs6 and such. And swat/sniper rounds? We go towned even harder. I planned on going to an airsoft game this morning at 9am, but I just couldn't get up because I was so tired.
