throwing up after drinking

i didn’t know where else to ask this question so i hope someone can answer? but every single time i drink i throw up, wether i’ve eaten while drinking, before, or after, i ALWAYS throw up. is there any explanation anyone knows as to why this keeps happening? or any tricks i could possibly try out to keep the liquor down? for a bit more context i only drink vodka, and i throw up even after only taking 2 shots (which isn’t a lot for me)
