Now that you mentioned beer, I am reminded that I am allergic to dark colored liquors, like bourbon. While drinking them, my nose swells up so I can't breathe, and then later, I break out in hives. The only thing that alleviates this is benadryl. So that's a bona fide allergy. Needless to say, I don't drink them.I can’t drink beer without getting very extreme stomach pain. It started about eight years ago when we were living in Colorado. Sooo many good craft beers. The last time was at a neighborhood picnic. I had half a glass of beer and had to leave the party to go home and lie down. I gave up after that. I was never a big beer drinker, but I did enjoy a cold craft beer on a hot summer day. I have no idea what the trigger is. It’s never happened with anything else.
