Thanks everyone for your responses and I'm sorry that you struggle with this as well. Sundog you're right my SAD lamp is a life saver for me.

Widgets, a SAD lamp is a lamp for Seasonal Affective Disorder. This is from wikepedia: Light therapy uses a lightbox which emits far more lumens than a customary incandescent lamp. I started using it in September and I do notice a difference. It's not the same as the real sun, but it's a great alternative. This is the website where I purchased my lamp from (I have the Travelite)
