OP, could the short days be making your depression worse? Have you noticed a correlation to the season?
I use 3 things, starting in October, a negative ionizer, a very bright large halogen light hooked to a dawn alarm, and a light box at my office desk. All products recommended at cet.org
I also walk the dog every morning. These things help keep my mood from tanking in November. It did take some effort to get in a routine and more effort to notice I was doing better than in previous years/seasons.
