I hear you owl... I live in the "snow belt" in Northeast Ohio and it's dreadful in the winter time. It's cold, gray, no sun, very little daylight... and I know a lot of the Northern states are this way especially in the winter time. It's very hard on the mood. And makes it really hard to switch in the spring time too (for me, at least last spring I was really hypomanic and irritable and agitated during April and May). I know some people with bipolar disorder who use a light box during the winter months. SOme docs are leary of this simply because there are studies that too much time in front of the light box can atually trigger mania. I haven't used it, but again, I have heard of people using it as a treatment to avoid the horrible crusing depression in the winter time. Good luck with the winter.
