I moved to sunny California because of this having started out in Seattle which is known for being cloudy and rainy a lot. My mood has been way better overall and I find that spending a bit of time in the sun each day makes me feel as right as rain. I would go so far as to say my life is a lot better because of this as it prevented some self loathing behavior or unnecessarily prolonged melancholy sans medication.
Probably accurate to say I'm solar powered.
