In general, I sleep around 3-5 hours naturally. My body does not allow me to sleep any more than that. However, for the last few weeks that number has been closer to 10. I figured that has to do with the insane amount of allergies I have, so I wasn't really worried. Day-before yesterday I was up all night, and didn't get to bed till 10 AM yesterday. I woke up at 6. At around 9:30 I took some Adderall so I could study. By 11:15 I was tired again. On Adderall. I was asleep by 12:30. On Adderall. The fact that all this happened on Adderall and about 4 cups of Coke is what made me thing that perhaps it's not the allergies. I woke up at 5 AM today, went back to bed at 9:30, then woke up at 2PM. I've been up an hour, and I'm sleepy as hell again. Should I get myself checked out, or am I just being paranoid?
