To sleep, perchance to dream

I've gone to bed so early lately. The other night I crashed at 7:30, for God's sake. I certainly have no shortage of rest at the time being. However, it doesn't seem to help. I got nine hours of sleep last night and then spent half an hour hitting the snooze button before getting up for church. What gives? And it's not even like I'm trying to compensate, like, sleeping nine hours a night alternating with sleeping three hours a night. I've been getting good chunks of sleep pretty consistently for a bit here...yet I am never rested. Pretty soon (this goes in cycles) I'll hit the "what the fuck, I'm gonna be tired anyway, might as well stay up late goofing off" stage but I just wish I could wake up one morning ready to seize the day.
