Morning or Night Person?

[magnolia]

I used to be a night person years ago but have turned into a morning person. On week nights, I'm in bed by 10:00 or so and up any where between 5:00 and 5:30. On the week-ends, I can't sleep much past 7:30 or 8:00 or else I end up with a major headache, regardless of the time I go to bed (which on Friday and Saturday nights, it's usually midnight!).
