You have the classic symptoms of Candidiasis (yeast syndrome). Run don't walk to your nearest health food store and buy Dr. Crook's newest publication, "Tired, Oh so Tired!," and also Dr. Walker's book, "Olive Leaf Extract." You won't believe what a change in diet and a few herbal remedies (and Nystatin, if prescribed) can do in a short time, and it all makes such perfect sense. I went through this stuff for years with Drs. telling me to, "Just live with it and be grateful it's not worse." There's nothing to loose by reading the literature on the subject. Good Luck!
