I'm just a little envious. I tend to go to bed between 22:00 and 22:30. I get up at around 6:30. Unfortunately this doesn't feel like it's getting me enough sleep; I'm still very drowsy in the morning and don't feel as refreshed as I could. I also need a nap in the afternoon. And on Sundays, I could sleep all day long if nothing or nobody woke me up... sleep deprivation? And yeah, I will totally feel like a zombie if I go to bed any later than I usually do.
