Not that it's any consolation, but my daughter cries over South Park and the Timmy and the turkey episode.

Would it help if you had daylight simulating light bulbs in the house/office for the times when you don't get to use the light box? I'm probably not mentioning anything that your doc hasn't already said, but I've put in those bulbs in the house and the color spectrum isn't golden and subdued like with regular incandescents. Don't know if it's helped since the weather's just started getting really dreary this past week, but it really does give you the impression that you're in natural sunlight instead of artificial.
