SAD..Seasonal affective disorder.. how do you northern guys deal with it?

S'why mamas in the south tell their younguns to "go outside and soak up some sunshine". All things good come from the light.
Vitamin D. I read somewhere that we do not get vitamin D from the sun until our shadows are shorter than our height. Dont care. If I can feel it and see it, it helps. It doesn't bother me near as much as it did when I had to commute both ways in the dark. That sucks!!
