The expected...

You'll be really tired, fall asleep if your sitting down, your eyes might turn red and your brain will hurt - but ahh your 12...knock yourself out, just don't do it on a school night :D

If your going to to do, take in plenty of caffeine to keep you up and have a line of movies or tv shows ready - you need something to do, or even someone to talk to or you just loose motivation :P

Have...fun :/
:)

yeah...i've done it before - it wasn't pretty.

The next morning, your eyelids will feel extra heavy. I tried that last year. You'll want to go to sleep ASAP.You'll also feel a little bit dizzy. You should drink soda or drinks rich in caffeine so you'll be able to stay up.
And also make sure not to lie down or you'll fall asleep without noticing.
Good Luck

My experience

You'll just be really tired and cranky from lack of sleep.
