Sounds like acid reflux to me, it should be helped with a PPI medication and/or otc like maalox or something. It really sounds gross the way you worded it, lol, but it's really very common with us heppers. good luck
i'm the same, maybe try yogurt? or even over the counter antigas medication?
While waiting for your Dr. appt. I would eat lots of yogurt with active cultures and get a probiotic supplement like Culturelle which you can buy at Walmart in the stomach aid section. There are other probiotics which are cheaper but the Hepatitis Researcher that comes to Med help sometimes says the Culturelle has lots of good research showing it to be effective.
