I get up very early for work, so I try to be offline by 9:30 and in bed by 10 (usually that slips to 10:30 though). It's so annoying and depressing that the sky isn't dark when I'm going to bed; it makes me feel like a little kid.
At least the worst is almost over -- the 21st will be the longest day, then we'll start going back to shorter again.
I wonder how I would do in Alaska, with their even longer days/nights. It might be easier, since I wouldn't expect "normal" there.
