I've always lived far enough north that the difference in daylight between summer/winter is very significant. In June, the sun is up at 5:30 in the morning, and doesn't set until after 9. In the winter, it's sometimes not light by 9AM when I go to work, and it is pitch black again by 4:30. It doesn't help that it is cold as hell at the same time that it is dark all the time. My sleep cycle tends to be very sunlight dependent, so I'm seriously dragging all winter, since my body wants to still be asleep when I have to get up, and by the end of the day, I'm already shutting down. Daylight savings time screws things up even more - turning the clocks back in the fall isn't terrible, but those first weeks in the spring are brutal.
