i usually get about 2-3 hours of sleep every night and im not very tired, but i get a lot of headaches, but when i get 4-5 hours of sleep i get so extremely tired and cant stay awake!! does this even make sense? does anyone else have this problem?

In theory, too much sleep will make you groggy. I work well around the classic 8-hour regimen, and if I hit 9, I'm a zombie all day.

And too little sleep will make you feel worse than if you never slept at all. For me, it's been better to pull all-nighters than get two hours.

Do you take naps? That'll screw you up if you're not careful.

:confused: My extremely amateur conclusion would be that you don't get enough deep sleep for it to matter at 2-3 hours, but at 4-5 you get just enough to feel groggy. I bet even 6-6.5 would make a huge difference.

I feel your pain on this one, having fought weird sleep patterns since I was a boy.
