Thanks, I'll get Andreas' book. I'm interested in your comments re. tongue coating not being due to candida. I concur, even though I seem to match all the symptoms of candida, I don't think I have thrush (from pictures on net), the coating seems to be more of a 'deposit' - maybe from bad or incomplete digestion? I read a good analogy in an article which described the tongue coating as be analgous to the deposits on a car's exhaust pipe when it's burning oil or not firing correctly.
Can liver toxicity/dysfunction/sluggishness, whatever we should call it, mimic the symptoms of candida or CFS?
I don't think my diet is very bad so not sure what has caused the stones in the first place although I was overweight as a child and drank ALOT of Coke!
