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

I always used to think this was just baloney lazy bullshit. I'm in central Wisconsin.. go to work in the dark, sit in a office with a small window up above my head I can't see out of. Leave in the dark. When I get home, I just want to eat, and go to bed. No ambition. Lots of thoughts during the day..and just no energy to do anything. In the summer, the wife has a hard time getting me to come in by 10 on a weekday, having fun doing stuff. It's almost 8:30 and I'm not in bed yet.. odd for me right now.
Just wondering if any of you get this way in the winter.. and what you do, if anything, to get motivated.

I just got the f*** out of there and vowed to never go back lol. I grew up in central PA, winters have 3-week-long bouts of dark gray overcast with no direct sunlight. Many days where it almost doesn't seem like the sun came up at all. I would get pretty regular headaches as a kid and when the sun went away for more than 3 days or so I became very tired and unmotivated just like you describe. I now live in CO and the sunshine really does wonders for me I'll never live in a place without lots of sun again. Sometimes we have storms move in where it gets cloudy here for 2-3 days and I still tend to get headaches and fatigue when that happens.

I will live anywhere in the U.S. besides the Northeast or northern Midwest, just can't handle it I'm afraid I'd end up going insane.
