Health is definitely something that will be affected with no sleep. Razor is right, it WILL drive you insane.
Whenever I stay up late lately, which I always used to do, I find that I start to get swollen glands in my neck, get a stuffed nose, and almost immediately feel like I've got some sort of sinus infection.
Razor kind of reminds me of Tyler Durden from Fight Club. He was a character that had insomnia, and because of it developed split personalities. "With insomnia, nothing's real. Everything is a copy, of a copy, of a copy."
When not getting enough sleep, you'll notice that things can seem more distant, and don't feel as real. If you're tired enough, you'll feel like you're almost constantly dreaming. You fingers may feel just a tad bit more numb, in fact.
GET SLEEP.
Side Note
Brain's post is quite interesting though. I'm still very new to all the things out here in the world. PR is the first step, then QiGong, the paranomal, life force, the spirit. Who knows?
