Anybody develop a random intolerance to alcohol one day? Like the “Asian flush” but you’re literally a cracker?

I used to have a pretty high tolerance to alcohol, like a “where does a girl THAT short put it away?” level. But one day, I have a simple shot of vodka in some juice, and my whole face gets really hot. Then I saw myself in the mirror, and thought “WTF, it’s NOT sunburn season, how is that even possible???” because I legit looked like I had one of those “below the sunglasses” sunburns, but esp heavy redness under the eyes, on the nose, and on my chin and ears, and they all felt hot. But I had been drinking that juice I mixed the vodka in for a while with no problems, didn’t eat any problematic foods that day, and have never had a reaction to alcohol like that ever, let alone that specific brand of vodka. I just kept thinking “I’m such a crackery cracker, not a hint of Asian unless it was a random relative from a thousand years ago, but why do I have the stereotypical Asian flush going on???”
