IME, nausea was noticeable the first few times I did full MAOI doses of oral harmalas, but since then...nothing, whether oral or vaped.
I think it's just a stage, getting rid of crap etc.
In hindsight, I would have worked with harmalas alone, building steadily up to full doses, I think that's the trick, rather than diving straight into home-brewed ayahuasca, or whatever...
“I sometimes marvel at how far I’ve come - blissful, even, in the knowledge that I am slowly becoming a well-evolved human being - only to have the illusion shattered by an episode of bad behaviour that contradicts the new and reinforces the old. At these junctures of self-reflection, I ask the question: “are all my years of hard work unraveling before my eyes, or am I just having an episode?” For the sake of personal growth and the pursuit of equanimity, I choose the latter and accept that, on this journey of evolution, I may not encounter just one bad day, but a group of many.”
