Short answer: Book a medical and medication review and line up integration support before you worry about dieta details. Safety and aftercare are the high-leverage steps; everything else follows.
First: medical and medication review
Ayahuasca pairs DMT with MAO-inhibiting harmala alkaloids, so combining it with SSRIs, SNRIs, or other serotonergic medications can cause serotonin syndrome, a potentially fatal reaction (Malcolm & Lee, 2017). The brew also raises heart rate and blood pressure, and while ceremonial use is described as having a comparatively wide safety margin, that margin depends on screening and no interacting drugs (Gable, 2007). See a clinician early, and never adjust medications on your own — washout timing depends on each drug's half-life.
Second: book integration before you travel
The days after a retreat are when insights either take root or fade. Arrange at least one post-retreat integration session in advance so support already exists when you get home. Clinical models treat preparation and integration as a single continuous arc that can be supported without anyone administering a substance (Gorman et al., 2021).
Third: clarify intention, then handle dieta and lifestyle
Write an open-ended intention, and tend to your mindset and setting — research treats context as a central determinant of outcomes (Carhart-Harris et al., 2018). Then follow your center's dieta guidance, which exists partly for pharmacological safety, and in the final two weeks prioritize sleep, hydration, and reduced stimulants.
Why the order matters
People often start with dieta rules because they feel concrete, but the steps that prevent emergencies and protect outcomes are the medical review and the integration plan. Get those locked in first; the rest is refinement.
