To sleep or not to sleep?

Today was my Wednesday double block. It always seems like such a long class to have, especially in the morning, but every time I have gotten back to my room, I find my roommate still asleep. I find this humorous, but I am also slightly envious of the rest my roommate is getting. I feel like I have gotten so much done and yet I do love my sleep. I find that is how most mornings go when I wake up earlier than 8:30. I feel tired for the first few minutes and then I wake up in the morning air. If I slow down and stay still for too long however; I regain all the tiredness I did not get rid of while I slept. This makes me almost fall asleep in classes and while reading textbooks. It seems to flee quite quickly as soon as I start doing some thing that is of any interest to me, or requires me to actually interact with; example: homework, computer, sports activities.
