I'm definitely not a night owl. If I lie around I get tired by like 9pm, especially in winter when it's dark. xD I get up pretty early for uni during the week and on the weekends I usually wake up at the same time because I must have an internal clock going. If I go back to sleep, my head feels kinda funny for the rest of the day so I usually just get up.

I used to stay up to all hours chatting to people online and then sleep in half the day, but I guess I grew out of that. xD
