So.... out of complete curiosity... totally hypothetical question... Do not concern yourself at all... How long can one actually be awake without like... dying? Or.. something else equally sucky happening? Like accidents.. because I'm 99% sure I just sprained my ankle...
Also, on an even more serious note, Ravenclaw is having practice Sunday morning, bright and early. And by that I mean 9 AM because let's be honest I can't handle being up with the sun.
Be prepared to work well into lunch, so eat some friggen breakfast.
