I tend to get really bad headaches, body aches, and obviously major stomach issues, it feels like the flu if it’s bad enough and I can potentially feel some lingering effects for a couple weeks. Strangely enough I’ve never had any sort of issue with any kind of wheat or rye based alcohol, even though I know it’s not considered Celiac safe, obviously. I feel almost guilty that I indulge in that stuff once in a while because I know it’s probably not good even if I don’t feel anything, but it’s just never been a problem for whatever reason
