sudden intolerance to hard liquor at age 22?

hi guys! over the course of the last few months, it seems that my body has lost the ability to digest hard liquor properly. i’m a 22-year-old woman in perfect health. it’s also worth nothing that i am taking a low-dose SSRI, but have drank on it for the last 3 years with no issues.

the problem first began earlier this summer when i had two shots of tequila (something that’s never been an issue for me) and ended up throwing nonstop in the following 24 hours, leading to me ending up in urgent care. since then, i’ve drank, but i’ve avoided any shots or mixed drinks, just beer. i’m not a super heavy drinker (i maybe drink once every other week?) and this wasn’t a problem.

friday night, i went out and had 3 beers, returned home totally fine. saturday night, i went out and had two beers and a vodka soda, and ended up throwing up twice in the morning and have been bedridden from nausea since. i had initially thought i just had a tequila intolerance but it’s seeming like i may have some sort of issue specifically with hard liquor.

has anyone else encountered this? if i can’t drink cocktails for the rest of my life, that’s honestly totally fine – beer does the job for me, haha. but i’m just concerned that there’s an underlying problem here or some sort of root cause behind why my body can’t digest alcohol.
