I live in Houston, and have problems with SAD. Even though I absolutely love fall/winter and colder temperatures, I've been very in-the-dumps lately as our local weather transitions to what counts as "winter" here. Need to start taking VitD again. For reference, I grew up in southwestern Oklahoma (far enough north to have snow and winters where the cold/ice was a problem), and lived in Austin from 1996-2005.
