The more reading I do about FMS the more it scares me. I have all the autonomic dysfunction (anhydrosis, mottled skin, migraine, heat/cold intolerance, high heart rate at night, low blood pressure ...) in addition to my cognitive challenges, and, of course, lots of pain and chemical intolerance. I've been having b12 injections for over two years. I think it helps me sleep, but I'm not aware of any other obvious benefit. I take 2000 D a day. As it happens, my naturopath has me on a gluten-free, no dairy diet for a few weeks to see if that helps. We are also trying rhodiola for adrenal support. I have tried many supplements and diet programs. Whatever is happening to me seems to be outside of the diet realm, but, as I said, am trying the gluten free diet again.
