I am much more down in the winter, even though right now I'm stable. I hate the cold grayness of it. Especially this winter. We're looking at more snow for Thursday which I am just totally sick of...anyway, I have a happy light that I use sometimes. I haven't used it consistently to be able to tell you if it works well or not but I did enjoy it last time as it felt warm on my face like sun does. Worth a shot. And my mom said tanning really helps her in the winter time because it's mimicking sunlight but there are other health concerns with that so you'd have to choose for yourself whether to risk it or not.
