Ayahuasca dieta: which one do you follow and why?

Has anyone found a difference based on which diets they follow?

My 1st shaman mandated a vegan diet (+no sex/ salt/ aliums/ refined sugar). Once I’ve had since have allowed white meat pretty much up until the day. Some have allowed only fish.

I’ve always gone back to the vegan diet out of fear but struggle to get enough protein.

My question is: what are your non negotiable, and why, when it comes to the dieta?
