Sudden alcohol intolerance?

105 lbs. 5”3. 27 female. I was able to drinnkk up until last summer. Within the last 2-3 months, it seems I always have to throw up after I drink. I feel the urge to throw up and I feel better afterward. No other symptoms. I don’t drink as much anymore. I never do liquor. Usually wine, seltzers, or beer. Even after 3 drinks I feel the need to puke.

Has this happened to anyone else? What testing did you get done? Any advice? How did you realize you had an intolerance or allergy?
