Jody-- Thanks for pointing out how functioning can vary depending on weather, which in turn seems mediated by other factors (geography, a person's individuality). I do better in warm, dry weather, and I am lucky to live in a climate that provides such weather most summers (not this one, alas, a bit too cold and foggy). I do need sunglasses constantly for the glare. Late fall and winter are definitely worse for me. However, I don't have to deal with the extreme heat and humidity of the southeast U.S. or the extreme heat of the desert SW. Reminds me of Slayadragon's posts on mold patterns in different geographical regions... Take care, J.
