I won’t go through all of the details since the other reviews already do. I just want to go on record as another person whose life was immensely improved by this book after suffering from yeast / chronic fatigue type symptoms for 5 years. Its been 3 years since then, and things are still great. You may also be interested to know that Dr. Clark charges very reasonably at her own practice – i.e. she does not seem to be in it for the money. Great person, great mind, great book.
Also, check out the self-health resource center listed at the back of the book: they have almost everything she recommends and at amazingly reasonable prices.
