Beer and wine make me sick, but liquor is fine.

Does anyone know why this could be? I’ll be 29 in a few weeks and I’m at a point where I can’t have any amount of beer or wine without nausea, diarrhea, and sometimes vomiting the next day. I’ve come to realize I can drink a good amount of liquor just fine, although I’ve really only tried this with clear liquor (if that makes any difference).

For context, I’ve had GI issues for a while. Diagnosed as IBS, but an IBS diagnosis doesn’t tell you shit about what’s going on with your body.

I really love beer and drank it for years with no issue, so it’s a bummer that I can’t partake anymore. I’ve mostly just been drinking vodka sodas when I go out because I know they’re “safe”. Last weekend I pounded back tequila gingers at a cookout all day and felt great! What gives?
