Hey Jay Rough,

I know what you're talking about. The nasty "acidic" (sulphur-tasting) burps... I guess it's a warning like: "Watch out... you're in for something you're not going to like". Anyway, I had them a number of times. I was told they are a result of indigestion (out of over-eating or eating stuff in a real bad combination) and I was given antacids to cure them. After a spoonful/tablet of this antacid, I would be okay within an hour or two. Or I just had to keep walking around the house to try and digest the stuff that refused to pass through the intestines. But everytime I ignored these funny-tasting burps, I ended up blowing chunks or almost. Eventually, I began to take them as a warning.

In my case, it was just indigestion.

Hope this answers your question.
