I'm not allowed to have caffeine at the moment because of my meds. But when I feel tired and I want to stay up, I get my dog and walk for a bit. That should do it.
hmm lets see....probably when im watchin some kool movie...or eating or drinking something....
as long as i dont see or remmber my school and books...i keep awake...
also when the lights are on i dont sleep....i love being in totally dark when sleeping...
