Beer makes me feel sick but I can drink literally anything else?

I physically cannot drink beer. I always only manage to drink half a can before I start feeling extremely sick, doesn’t matter which brand or the percentage. I get nauseous, I feel feverish, my stomach hurts extremely bad and I feel like I’m gonna throw up at any moment… Also doesn’t matter if I’ve eaten well or not or if I’ve had anything to drink before it or not.

I’m not celiac/gluten intolerant as far as I know, what could it be that I’m reacting so violently to??? Does anyone else have this problem? I’m thinking of trying gluten free beer just to see if it works better for me, but either way… Huh???
