Does what it says in the title - sorts out Heartburn. It's easy to understand. Goes against all the perceived wisdom of Gastro Consultants who just want to prescribe strong drugs. Sorted my heartburn out very quickly and I haven't taken any drugs since.
Have had severe gadtric reflux for decades. Family got cancer from the same so went for a camera down. Scary being pre cancerous but this book has even allowed me to stop the arthritis xausing ant acids and be reflux free. So yep. Impressed.
