How to settle my stomach?

I’ve noticed I’m running into a problem when drinking that’s a bit odd. No matter how much alcohol I have, my stomach just does not settle well. It started when I had some shots of hard liquor. Of course, it’s not for everyone, but something about the way it sits in my stomach, mixed with the taste just makes me instantly hurl. So I switched over to just drinking beer. I like the taste of most beers, but I run into the same problem. My stomach just feels awful and full and I puke fairly early into the night, not even getting drunk.

It’s not like I’m drinking all the time. Sure, I am in my early 20s and drink with friends, but it’s usually only in those social situations that I do drink. It’s even weirder because this is a recent development. The hard liquor thing only started in the past year and the beer thing only started in the past two weeks.

I’ve tried eating beforehand, doesn’t help my stomach. I’ve tried drinking water and chasers, doesn’t help my stomach. It’s gotten to the point that I’m not even getting drunk before puking. I seriously don’t know what the problem is, whether it’s a problem with my stomach or my eating habits or my current weight, I have no clue. I wanted to see if this is just a me problem or if this is common, and potentially how to fix it. Because for now, I will not tolerate the lightweight slander.
