I've been awake for 36 hours. And I'll probably be awake for another hour or two. This is my story: I woke up Sunday at noon. Yeah, I know, that's late. I get back to the dorm that night and attempt to sleep at 8 PM since I have to get up at 4:30 AM for clinicals. The thing is, I can't sleep at all. So I'm tossing and turning all night and the next thing I know, it's 4:30 AM and my alarm is going off. I'm not sure why I can't sleep. I roll out of bed, get ready, and do a 12 hour shift (6 AM-6PM.) And now I just got back from doing some cardio and weights. How I am still awake and have energy to spare for some studying? I have no idea.
