Exactly my problem. I just can't sit down and study anymore. I'll be heading to bed in 4min or so, only to wake up in 5hrs so I can study for 6hrs lol. Cram session. Again. Tomorrow I HAVE to sit down and study for my law test, there's no way around it.
What happens is I'll say "ok, I'll study at 7pm". Then I'll realize hey, I have to pick up my brother at 4:30, and I'll get home around 5....that leaves only 2hrs to myself. Ok, I'll study at 8 instead. When 8 starts creeping up I'll put it back to 9. Pretty soon it's midnight and I'm still putting shit off.
