You REALLY didn't get 3 days sleep, huh?
Man, I couldn't do it! Although I did sit up all night long once playing a game (long time ago, Realms of Arkania: Blade of Destiny)...started at 8:00 p.m. one night and found myself at 9:00 a.m. the next day still playing it (it was a Saturday).
Play on, brother!
