Are you, by chance, on Eastern Standard Time? Just wondering. I know how you feel though. There have been times when I spent all night drawing because I was too energized to sleep (my profile pic was the result). We had the internet at my house for a short time last winter, and I would be up until 3-4 in the morning reading fanfiction on my Nintendo 3DS. Where my health is concerned, it's probably a good thing the internet was later shut off!
