What do you find helps you the most with acid reflux/heartburn? I eat tums like candy and take zantac, but I'd like to see if something else would help because I get it pretty bad. My Dr tried getting me an Rx but my insurance doesn't cover a lot of it due to similar items being sold over the counter. 😔
