Selective 5-HT3 antagonists are probably about as good as it gets for combating psychedelic nausea effectively with as little of their own psychoactive contribution as possible. That said, nausea is a complicated thing and there's probably still ways it can worm its way into your subjective experience despite having the best meds. You've just got to try it and hope for the best.
I think it's theorized, but not confirmed, that psychedelics at least partly cause nausea through their action at 5HT3.
