I Am Not a Morning Person
For me, it's not that I'm cranky or wake up on the wrong side of the bed. I just have a hard time waking up before 11. When I do wake up before my preference, I'm drowsy pretty much the whole day up until around 5PM. I think I get a decent amount of sleep...I usually hit the hay around 10--11 PM.

I'm a night person rather than day.
