suddenly cannot stand drinking alcohol anymore

Hi all, had a night out tonight in which I realized I literally cannot physically stand to drink alcohol anymore. Im only 22 and have never been a heavy drinker, I get drunk maybe every 3 months or so when I go out and I used to be able to take multiple shots, drink mixed drinks all night, etc etc. I do typically throw up every time I drink, but not until the end of the night when I’ve accidentally gone over my limit. However suddenly, drinking any amount of alcohol, mixed or not is just vile to me and I immediately start feeling sick. I started tonight with a small amount of vodka mixed with peach juice, and every sip was hard to get down. After that one drink, my friends and I took a shot and I immediately threw up because of it. I felt completely fine once I threw up and a couple hours later tried to have another mixed drink, however it still made me squirm trying to drink it.

I’ve noticed lately every time I drink it gets harder and harder to get down and just wondering if anyone might know why? I’m still young and really do not drink often at all so it’s hard for me to figure it out. Also if anyone has any suggestions on how to get around this I’d appreciate it because I definitely enjoy having a nonsober fun time (:
