I found the first portion of this book very useful, although later it's padded with unexceptional recipes:
The Acid Watcher Diet
Dr. Jonathan Aviv's findings align closely with my own experience. If the book had been available a couple of decades ago, it would have spared me years of trial and error as I figured out my reflux triggers.
He points out that the so-called "silent reflux" has often been misdiagnosed. That was my experience when I had a particularly bad bout. (I had trouble swallowing and breathing in deeply, but no regurgitation. Several doctors could not figure it out, and one misdiagnosed it as COPD.)
By the way, he explains why taking apple cider vinegar is
not good.
