Having been through my own food weirdness (thankfully not as bad as yours sounds), I sympathize.

I have one of those weird opposite recommendations--feel free to try this or ignore it as you see fit. Peppermint tea is sometimes used as a remedy for upset stomach. However, a while back, I saw a caveat that people who have acid reflux should avoid peppermint because--wait for it--it can cause the sphincter between the esophagus and the stomach to temporarily weaken and/or not close fully. Since you have the opposite problem, this effect might be desirable.

Either way, I wish you the best of luck.
