This book has given my son his life back (and mine). We have gone through numerous doctor visits and testing, but only this book has provided us with the much needed guidance and knowledge. My son was 12 years old when diagnosed with IBS. He was tried on different prescription medications, but Heather's suggestion of peppermint oil was not only more effective, but is also a nature based product.Truly what has been the best advice is to start off the day with a soluble fiber and eat these foods as much as possible. My son is now regaining weight and his energy level has increased.I am a nurse and was skeptical at first that I could find the answers from this book and not from his physicians. However,this book and Eating for IBS, also by Heather, have become my bibles.
