Can no longer tolerate beer/wine/mead

So fairly recently I’ve discovered that my stomach can no longer tolerate beer, wine, or mead. It feels almost like an air bubble has formed in my stomach that arises when I drink any of these. It is uncomfortable but not painful and doesn’t cause me to vomit or anything. I can drink liquor just fine though. There are no other foods or drinks that cause this reaction.

Anyone else experienced this? I have no idea what it is.
