I first took this book out from my local library for my wife, she was very impressed with the features in the book, concerning a condition that she as suffered with since she was a child, that she asked me to purchase a copy. My daughter also asked me to purchase a copy for her friend who as just had a child with the same condition. Since receiving the book my wife and especially my daughters friend, have found out ways to alleviate some of the painful effect of this very bad condition. I say that if you suffer or know any one who suffers from this condition, do read this book.
