So you’ve decided to sit with ayahuasca. Maybe you’ve been reading about it for years. Maybe a friend came back from Peru looking suspiciously lighter and wouldn’t shut up about it. Either way, you’re here now, trying to figure out what to actually do in the weeks before you drink the brew — and there’s a lot of conflicting advice floating around.

Here’s the short version: ayahuasca preparation matters more than most first-timers want to believe. The plant medicine itself is only one part of the equation. What you eat, how you sleep, what you put into your body and mind for the weeks leading up to ceremony — all of that shapes what happens when you finally drink. This is true whether you’re heading to a small jungle lodge run by a Shipibo family or a polished retreat center with bilingual facilitators and a chef.

What follows is the honest, practical version of how to get ready. No mysticism for the sake of it, no fear-mongering, just the things that genuinely move the needle.

What Is an Ayahuasca Ceremony, Really?

Before we get to the prep, it helps to know what you’re preparing for. An ayahuasca ceremony is a structured ritual built around drinking a brew made from the Banisteriopsis caapi vine and, usually, the leaves of the chacruna shrub. The combination produces an experience that can last anywhere from four to seven hours, sometimes longer. Indigenous Amazonian groups — the Shipibo, Shuar, various Tukano peoples — have used it in healing contexts for generations.

What the night actually looks like depends entirely on where you go. A traditional jungle ceremony with a curandero deep in the Peruvian Amazon might involve a small group, a long night of icaros (the medicine songs the shaman sings to guide the experience), and very little Western infrastructure. A larger retreat center might offer the same medicine inside a purpose-built maloka, with onsite medics, mattress pads, individual buckets, and a structured integration program in the morning.

There are also urban centers that cater to people working through addiction or trauma, churches like the União do Vegetal where ayahuasca is sacrament, and underground circles in countries where the brew sits in legal grey territory. Each setting demands a slightly different posture from you. The preparation principles below apply to all of them, but the stricter the lineage, the stricter the dieta tends to be.

The Dieta: What It Actually Means

The Spanish word dieta gets translated as “diet,” which is technically correct and totally misleading. In the plant-medicine world, the dieta is a whole protocol — food, behavior, substances, even your media intake. The idea is to arrive at ceremony with a body and a nervous system that aren’t fighting fifteen other things at once.

Most reputable retreat centers will send you a list two to four weeks before you arrive. Read it. Follow it. Don’t negotiate with yourself about the bacon cheeseburger the night before your flight. Here’s the general shape of what they’ll ask:

• No alcohol or recreational drugs for at least two weeks before (a month is better)
• No red meat or pork, ideally no animal products at all in the final week
• No salt, sugar, spicy food, fermented food, or aged cheese in the days before ceremony
• No sexual activity — with a partner or solo — for one to two weeks on either side of the ceremony
• Cut caffeine down or out
• Reduce screen time, news, and anything that jangles your nervous system

Some of these have hard pharmacological reasons. Aged cheeses, fermented foods, and certain meats contain tyramine, which interacts badly with the MAO inhibitors in the ayahuasca vine. The reaction can spike your blood pressure and make you genuinely ill. Other rules — the sexual abstinence, the screen reduction — are more about preserving the kind of internal stillness the medicine seems to respond to. You don’t have to believe in spirit possession to notice that you go deeper when you arrive uncluttered.

Medications: The Conversation You Cannot Skip

This is the part where I get serious for a moment. If you’re currently taking prescription medication — particularly SSRIs, SNRIs, MAOIs, lithium, tramadol, or anything for blood pressure — you need to have a real conversation with your prescribing doctor before you book anything. Not after. Not on the plane.

Ayahuasca contains its own MAO inhibitors. Stacking them with pharmaceutical antidepressants can cause serotonin syndrome, which is a medical emergency, not a metaphor. Most retreat centers will ask you to taper off SSRIs at least six weeks before ceremony — sometimes longer, depending on the drug’s half-life. Fluoxetine, for example, lingers in your system for weeks after your last dose.

A good retreat will refuse you outright if you haven’t handled this properly. That’s a green flag, by the way. If a center waves you through with a current SSRI prescription and a shrug, walk away. They’re either uninformed or careless, and neither is what you want from the people pouring your medicine.

Setting Your Intention (Without Overthinking It)

Most retreats will ask what your intention is. People panic about this. They think they need a profound, perfectly worded mission statement. They don’t.

An intention is just an honest answer to the question, “Why am I here?” It can be small. It can be confused. “I want to understand why I keep ending up in the same kind of relationship” is a perfectly good intention. So is “I’m grieving and I don’t know how to move through it” or even “I’m curious and I want to meet this medicine.” The brew has a way of finding what you actually need, regardless of what you told yourself you wanted. But the act of articulating something — writing it down, sitting with it — focuses you in a useful way.

What I’d caution against is going in determined to have a specific kind of experience. People who arrive demanding visions, breakthroughs, or contact with deceased loved ones often have the hardest nights. The plant doesn’t take orders.

The Last Few Days Before You Travel

The week before you fly is its own little chapter. Your job here is to arrive intact. Sleep more than you think you need to. Hydrate aggressively. Pack early so you’re not panicking the night before. If you can, take an extra day on either end of the retreat — flying directly from a transatlantic flight into ceremony night is rough on the body, and most experienced facilitators will tell you the same.

A few practical things worth doing:

1. Print your travel documents and insurance details — many jungle lodges have spotty internet
2. Bring a flashlight, loose comfortable clothing, and a journal
3. Pack any non-prescription items you rely on (electrolytes, ginger for nausea, a familiar pillowcase)
4. Tell someone at home where you’ll be and when they should expect to hear from you
5. Go easy on social plans the week of departure — your nervous system is already shifting gears

If you’ve been reading endless trip reports on Reddit, consider closing the tabs about a week out. At a certain point, more information stops helping and starts crowding out your own experience before it’s even happened.

What Most People Get Wrong

The biggest preparation mistake I see — and I’ve sat in enough circles to see it repeatedly — is treating the dieta like a checklist to grit through, then snapping back to old habits the moment ceremony ends. The integration period after ayahuasca is at least as important as the prep, and the first week or two after a retreat is when the work actually gets done. That’s when the insights either take root or fade into the background hum of normal life.

Another underrated mistake: arriving exhausted. People often book ayahuasca during their most depleted moment, hoping the medicine will resurrect them. It can. But a fried, sleep-deprived, over-caffeinated nervous system is a hard place to drink from. If you can, arrive a little rested rather than a lot desperate.

And one more, gently: don’t bring anyone you’re not fully aligned with. Couples can absolutely drink together, and many do beautifully. But if there’s unresolved tension, the ceremony will surface it whether you wanted it to or not. Plan accordingly.

Choosing Where to Sit

Preparation also includes choosing well. Look for centers with experienced facilitators (years, not months), real medical screening, a clear policy on medication interactions, and integration support that goes beyond a group breakfast the next morning. Read participant accounts that aren’t on the center’s own website. Ask whether the curanderos have an actual lineage, and whether they’re paid fairly.

If a center won’t answer questions about safety protocols, or if their intake form is two questions long, take it as information. The places worth sitting with tend to ask you more than you ask them.

For readers ready to take this further, a range of curated ayahuasca retreats can be browsed and booked through the marketplace, which can be a useful way to compare lineages, settings, and pricing in one place before committing. Either way — start the dieta early, handle the medication question honestly, and give yourself time on both ends. The medicine will do its part. Your job is to show up clean, rested, and willing.
