Why won't my 28 year old body let me have a drink or two?

I drank only 3 glasses 3 hours ago and now I threw up everything 😭😭 I'm in the bathroom and don't want to get up(sorry if tmi, just venting)
I used to drink so much when I was 15 (not trying to brag, I was stupid back then) even drank a half a bottle of a big crown whiskey bottle ike ugh now I can't handle anything 😭😭😭
