My boyfriend discovered coffee was the main culprit for him. Then when I got him to start taking Metamucil (capsule form) every day, it made him feel great. Now he only has trouble if he drinks real coffee, dairy, or skips his Metamucil.
He tolerates Foldgers Simply Smooth coffee much better. It is low acid.
I should add that when I developed gallstones, I vomitied every morning while I was trying to brush my teeth.
Good catch, that must be it...I'll cut down on the coffee definitely. If my stomach already has acid from gastritis, pouring coffee on it is like adding fuel to the fire. Thanks for your advice! :)
