Oddly enough one of the most effective treatments for excess stomach acid is to drink about a tbls full of apple cider vinegar. The shock of the added acid from the vinegar will cause your body to turn off the pumps that form acid and you will feel better in about 15 min.
Hi DoctorShemp Funny you ask that because I was just throwing up this morning from stomach acid. It's like that burning feeling in your throat and makes you want to burp? I believe there is some medicine that you can get at Walmart or a local drug store called gaviscon for a few bucks. Hope you feel better! :-)
