I'm pretty sure that I've been awake for over 24 hours.
I'm pretty sure that before I woke up 24 hours ago I'd only had about 2 or 3 hours sleep.
I'm pretty sure that before that I'd been at my desk for about 20 hours.
“Pretty sure” is about the best you'll get out of me at the moment.
I feel all light, and fluffy... :P
I think I'm gonna go and float up to my bedroom.
