How do I drink without my stomach wanting to kill me?

Hey! Not sure if I can even get a real answer, but it’s a genuine question. I have bonfires, and enjoy hanging out with friends, but I’m not a big drinker, I find that well mixed drinks are good, but anything else tastes awful, jack and coke, or just the overall taste, Tito’s, Long Island, fireball all of it, burns my stomach like hell on earth, probably just my body but I just turned 21 I’m still young, I want to be able to drink and get drunk but enjoy it. Any tips or drink ideas for a guy like me?
