If I go to sleep at that point, I'm out. Done. I'm sleeping through the alarms or turning them off in my sleep, and that's a guarantee. No waking me up unless someone is physically dragging my ass out of bed, and that's still just a maybe.
I have the opposite problem right now, its 1AM and I want to sleep now but I dont want to wake up before 9 or 10 AM and if I sleep now I'll wake up at like 7AM
So I should wait a few hours or else I'll likely oversleep and I know I'll hate it but I'm very tired... I could also just not oversleep but I know myself and I surely will :P
