I cannot even begin to sum up how valuable this book has proved to my life. Having spent over 6 years going back and forth to my GP with digestive problems, abdominal pains, acid reflux and suspected gallstones, I finally decided to give this eating plan a go. I am pleased to say that after suffering for 6 years, this book has helped me to be pain free from the first day that I changed the way I ate. If you have IBS or GERD or indigestion, ulcers or colitis then I urge you to try this diet. It works a treat!
