I think it's horrible advice. As you have said yourself to countless of other people, everyone's different and thus will react in a different way.. Taking a higher dose to counteract nausea should work in theory (no ego, no body, etc.), but have you ever seen someone puke on a higher dose of 5-MeO-DMT..? No you haven't, though I have and comparing the two experiences, I would say that the person in question had far more trouble with the latter (high dose 5-MeO-DMT). I've also had a fair bit of nausea on a higher dose, but not during the entire experience, only in the beginning.. Nausea doesn't magically dissapear when you take a higher dose, it's all highly subjective.
