Aw man, I know that feel bro.
Honestly, the past three months of college have ******** up my sleep schedule so bad. It's at the point where it doesn't matter what time of day it is or how long I've been awake or asleep. 98% of the time, I just need to get in a comfortable position and I'll be out like a like.
Up until today, I hadn't slept more than a few hours all weekend, and no sleep between Monday Morning and Tuesday afternoon. I finished my last assignment, turned in my portfolio around 2pm, then went straight back to my dorm to sleep for several hours. Now I'm awake and messing around on the net, I'll sleep for another eight hours whenever, free day today C:
But I've also found that I can remain awake for three days and most of a four with little to no sleep. That was a really shitty weekend. I'm planning on enforcing a super strict bed time before midnight for about a week or two when I move back home next week to try and fix my sleeping. I've always been pretty nocturnal but the circles I have these days make it look like I lost a fist fight.
