Always get sick when I drink

As the title states, I always get sick when I drink nowadays. I’m a male, 33 years old and live a healthy lifestyle. Exercise minimum 3-4 days a week. Now granted, I don’t drink often at all. I’ll drink once every few months. Sometimes I may have a beer or two on a random night here or there.

This past weekend I went over to my buddy’s place. All I had to eat was a bagel with turkey and cheese before I started drinking. I had 2 or 3 Michelobs before I ate again (because my stomach was empty at that point and felt I needed to eat). My friend smoked a chuck roast and we made tacos. I had 3 tacos and continued drinking Michelob. I had 2 more but struggled through them. I felt sick from there on out and couldn’t drink anymore. I felt so bad that I made myself throw up twice throughout the night.

Throwing up after drinking is pretty common for me, but my friends are fine. Is the problem that I don’t eat enough before I drink? Maybe it’s what I’m eating prior to drinking? Is it that I ate a little, drank, ate again then drank some more? What’s a good plan going into the next time I want to drink with friends?

Sorry in advance if this is the wrong sub for this
