I have a family and personal history with pretty severe SAD but have been able to keep my head above water pretty well this year. Don't really know why my approach has been more successful this winter than past (probably the MJ) but I'm hoping it will last or at least that by the time it turns around it won't be too bad. It's looking good so far and the further in we get to the darkness, the more optimistic I am that it won't be so bad.
Just move to southern/southeast Alaska where you can pretend you love the constant darkness and the flittering of the temperature around the 32˚F mark with constant precipitation so that it rains, then snows, then rains, then freezes the slush solid with below 0˚F, then rains and snows on top of that and then the wind blows 60mph off the tops of the mountains... just pretend you love it.
Until you get your oil check and can take off to Hawaii for a couple weeks just before you're about to crack and get a few months worth of vitamin D and spam sandwiches and get drunk off of cheap island moonshine.
Then you can head back to Alaska and act like you love the summers, which are invariably cold and cloudy and just rainy enough that it feels like God is spitting on your head.
