What up guys.

I have to get up early for 8 AM classes (at around 3:45 AM, accounting for my whole morning routine, my commute, and all that), & I'm trying to get 8 hours of sleep... but I can't do that because my body clock's all out of whack. I've noticed that after I fap, I get tired & fall asleep really quickly; it's an effect that I can't replicate with complete darkness when I go to sleep. But I don't want to fap every day. Being horny also keeps me awake; I can't sleep when I'm horny.

What do I do?
