Oh it's rough on people who aren't used to it, and the winter is horrid on people with SAD (which is thankfully rare around here).
I don't loose any sleep from it. I've lived here most of my life and so it doesn't bother me.
I love the winter up here Tekla, for that reason alone... On the darkest days it doesn't even get to the point where you can say that there's "daylight" out there, and the snow combined with that means the whole world looks painted in hues of royal blue.. it's really quite stunning.
