Alc makes me vomit too easily

I dont drink very often (like once every 1-2 months) so maybe thats simply the reason. However when i do drink Ive never been able to drink enough to feel the effects without feeling like i need to or actually throwing up. Even just a seltzer is enough to make me feel like i wanna vomit. Im a relatively bigger dude too . Whats the method for being able to drink enough to get drunk without throwing up?
