I've been dealing with GERD and IBS. Had paraesophigial hiatal hernia surgery at Mayo's. Also been tested for food intolerances. Am doing both the FODMap diet and PPI's (which I'm nervous about). One trick that I've learned for temporary relief is a tsp of flavored vinegar, followed by water to get rid of the taste. Doesn't cure but does solve the immediate GERD problem.
