The best thing you can do is get yourself a Seasonal Affective Disorder lamp and use it while you work on the computer, an hour or two daily in the mornings. If you dont wanna spend too much money on it, get yourself a few very powerful floodlights. The lights have to emit at least 10K lumens on 1 meter distance, the floodlights are way more powerful than the SAD lamps anyway.
