Dude... any time I don't have to get up early the next day, I stay up till around 3:00 or 4:00, and wake up around 12:00 or 1:00.
For example: Last night. I stayed up until 4:00, and I've been doing similar things for the past few days. Problem is that I have a test tomorrow morning (my last one thank God) and since I've started to settle into this pattern and I woke up at 1:00 this afternoon, I'm not going to be able to fall asleep until late, which means I'll be tired as hell for the test tomorrow. I'm pretty much screwed.
It's really funny I found this thread because just a few minutes ago I was thinking how I need to stop myself from settling into this lifestyle. I really don't like waking up so late. In fact I've liked the past few weeks because it's been just tests, which means I have to wake up early but still get home fairly early. I like being up around atleast 11:00, I feel like I have a much fuller day.
Problem is that I have trouble getting myself to wake up if I don't really have to, as in for school. And I hate being tired, which I always am in the mornings. This summer I'm going to try to change that. My goal is 11:00. I know, ambitious.
