What kind of alcohol are you able to drink

I’m having a hard time going out sometimes because out of nowhere I’ll start feeling the discomfort. Sometimes I’m able to get away with it but lately more often than not I am getting discomfort while drinking and I have to keep throwing out my drinks. Is there something you guys do for prep when drinking or am I just effed for the rest of my life? I just drink casually with friends and I’m in college so I don’t want to feel too left out :(
