Clocks fall back this weekend in the US — how do you handle the early dark?

Daylight saving ends Sunday morning in the US (Europe already switched last weekend), and for a lot of people the sudden 5pm darkness is when the low days start creeping in. Last year a daylight lamp at breakfast and a lunch-time walk made a noticeable difference for me, even if it's not magic. What small things help you get through the darker months? No tip is too small.
