Hello and welcome to Mayo Clinic Connect @heal33. I am not a medical professional, however, was wondering if you might want to try to add or eliminate just one thing (Rx, food item, vitamin) at a time until you can isolate what is causing the heartburn? Of course any change in your Rx medication should be done under consultation of your physician to be safe. I see @jakedduck1 has also joined and is very knowledgeable so may have other recommendations and thoughts. Happy to have you join us!
