I suffered for a year before this book came to my rescue. Once I started having stabbing pains after I ate, a friend let me borrow her copy to seek some relief. After an endoscopy and a trip to the emergency room with excrutiating pain, I finally consulted the book and learned that my problem may go further than acid reflux. At my second trip to the ER I insisted on having my gallbladder tested. The ER doctor was not interested in going that direction, but he placated me and let me have an ultrasound. That revealed that I had an enlarged gallbladder and gallstones. I had surgery the next day to remove the gallbladder. Had I not read the book and become informed, there is no telling how much longer I would have had to suffer (the ER docs were content with medicating me and sending me home and not trying to figure out what was wrong). It helps to educate yourself when you know something is not right with your body, because doctors do not know everything. I had seen two doctors previously, and neither had an inkling that my gallbladder might have been my problem. I highly recommend this book to anyone that has digestive problems.
