My body's hating me right now... here's why:

A breakdown of my sleep schedule for the past week.

Saturday: wake up at 1:30... sleep around 5 (awake for 15 1/2 hours)
Sunday: wake up at 3:30... sleep around 6 (sleep for 10 1/2 hours, awake for 14 1/2 hours)
Monday: wake up at 12:30... sleep around 3 (sleep for 6 1/2 hours, awake for 14 1/2 hours)
Tuesday: wake up at 8... sleep around 2:30 (sleep for 5 hours, awake for 18 1/2 hours)
Wednesday: wake up at 9:30... sleep at 2 (sleep for 7 hours, awake for 16 1/2 hours)
Thursday: wake up at 10... sleep at 1:30 (sleep for 8 hours, awake for 15 1/2 hours)
Friday: wake up at 6 (sleep for 4 1/2 hours... though only had about 3 hours of solid sleep, awake for 17 hours currently)

To make things worse, I haven't been able to fall asleep very easily as of late. Last night I kept having short little dreams that would end aburptly and wake me up constantly for almost 2 hours. Three nights out of the week I woke up hours before my alarm and couldn't fall asleep for the life of me. I can't understand why, because I have the longstanding reputation of being the deepest sleeper, and that I could sleep anywhere or anytime. Now I'm struggling to keep my eyes open at 5 pm. What's wrong with me?

It's 11pm... and in 10 minutes I'll be cold knocked out. I don't wanna move till at least 8am.
