Considering the literature on PCOS is pretty slim, I was so pleased to have bought and read this book. While reading it, you'll have lots of "that's exactly how I feel" and "Oh, that makes so much sense!" pertaining to your PCOS symptoms. THis book also gives you alot of explanation and practical advice beyond the medical basics usually found on the subject. I'm grateful for this purchase and it will be a reference book for me for years to come.
