I rarely drink and after not drinking for like a year I tried it and couldn’t get drunk. Just sick. Tried it a couple more times and same thing. Does anybody know why?

Basically what the title says. I’ve never been a big drinker and I went like about a year without taking a sip of alcohol.(no real reason I just wasn’t going out like I used to and when I did I took a couple shots and felt nothing. Just that uneasy feeling you get when you’re coming down and your body feels like sh*t and your stomach hurts a lot. Like you’re gunna throw up. Just sick. I’ve tried drinking like 4 times after that and it’s always the same. Doesn’t matter how much I’ve had to drink either. I’ve take 3 shots back to back which used to have me pretty drunk and the same thing happens. I really haven’t changed anything in my routine leading up to this. The only thing that has changed is I started taking Buspar mid way through last year. Has anybody experienced anything like this? Is there a way to reverse it? What is happening to me?!
