I agree about the vitamin D. A couple of years ago my blood showed very low and have been taking D supplements since. I feel my absolute worst when the barometric pressure drops. For me it is not a mold or humidity issue ... just the pressure. Once the storm starts and the front is passing I get relief. I swear in the winter my body ache can predict the weather better than the TV meteorologists. They say one inch snow, but my shoulders are hurting like four ... sure enough we get four. :-)
