Straight answers about preparing for an ayahuasca retreat
Every claim on this site traces to a published source, and every article says plainly when the honest answer is “not yet” or “not you.” No promises of healing, no instructions for using anything.
Safety

- Is Ayahuasca Dangerous? What the Data Actually SaysThe honest answer is more reassuring than the headlines and more demanding than the romanticism. Both halves matter.
- Who Should Not Take Ayahuasca: The Contraindications, In FullRead this looking for reasons not to do it. That is the opposite of how most guides are written, and it is the point.
Choosing a retreat
2How to tell a professional center from a dangerous one, before you book.
- 10 Questions to Ask an Ayahuasca Retreat Before You BookEmail these to three centers and compare the answers. A serious center welcomes them. One that gets defensive has already told you what you needed to know.

Preparing
3A month-by-month plan, a readiness self-check, and what to pack.

- What to Bring to an Ayahuasca Retreat: The Packing ChecklistNothing here is glamorous and all of it matters. The goal is that the only thing left to do on the last day is be present.
The diet
2What each restriction is really for, separated by how much it affects your safety.
- The Ayahuasca Diet, Explained: Three Layers, Not One ListSearch this and you get endless lists of prohibitions, rarely explained. Once you know which layer a rule comes from, the diet stops being arbitrary.
- Do You Really Have to Avoid Cheese Before Ayahuasca?Yes — but not for the reason you have been told, and not with the fear you have been sold. The distinction matters more than it sounds.
The ceremony
3The shape of the night, and what to do when it gets hard.
- What Actually Happens During an Ayahuasca CeremonyNobody can tell you what you will see. But the shape of the night is predictable, and knowing it frees your mind from managing what does not need managing.
- Why People Vomit on Ayahuasca: The Purge, ExplainedIt is the thing people are most embarrassed about in advance and most grateful for afterward. Here is what is actually going on.
- How Long Does Ayahuasca Last? The Timeline From the First Cup to Day ThreeThe honest answer is "several hours," and the number that matters more for planning is not the ceremony. It is the days around it.
Integration
2The month afterward, where the change either happens or does not.
- Ayahuasca Integration: The Part Almost Everyone SkipsThe ceremony is not the work. The ceremony is the raw material. This is the work.
- The First 72 Hours After an Ayahuasca CeremonyThese hours matter disproportionately. Support in the immediate days reduces risk; the absence of it is where prolonged distress and impulsive decisions come from.
