I first started suffering with this dd when I was ateenager. Since then I haven't had a single day, or even a single moment when I've had a clear head. I never feel alert. It has improved ,as at one point I just lay down for 6 years!! Treatment for orthostatic hypotension helped but does anyone have anything that's helped in even a small way with the brain fog???? All sugestions welcome! I sleep for 12 hours each night and take a nap at lunchtime. I sometimes feel -no wonder I'm foggy! But I feel worse if I sleep less! Anyone had any luck with Ginko? Has a yeast elimination diet helped anyone?? Thanx! Love Patchwork..
