Welcome to Gaia! ::

This is one thing I have always been curious about.
How does lack of sleep affect you?

Myself:
12am, I tend to start doing the head nodding thing.
1am, I am about to fall out. Literally...if I was standing, I would fall on the ground, face-first, and still fall asleep.
2am, my eyes start to play tricks on me. I start seeing things...and I tend to get dizzy easily.
3am, I get my second wind. o_o I start to act really hyper...it's kinda creepy.
4am, still on my second wind rush. xD
5am, starting to feel the lack of sleep coming back to me
6am, I normally fall asleep here if I pass 1am.
7am, I'm up and at it. I just start my day as if I had a whole nights rest.

Mind you, this is on a friday or Saturday.
I could never do this on a Monday-Friday and survive. xD

I don't think I have insomnia...because I can fall asleep easily, but I do have nights where I don't sleep well at all....Hmmmm

Random: I always seem to start frezzing around 1am to 3am. gonk And I am a warm-natured person!

Questions:
What are you patterns?
Can you stay up a whole night without any troubles?
Do you have Insomnia or just Insomniac symptoms?
Do you get cold when you stay up late? (I do!)
