Start with the practical: confirm whether any medications you take require washout, and if so, begin that process with your prescribing doctor as far in advance as possible. Follow the dietary restrictions for at least seven days before ceremony, longer if your baseline diet is heavy on stimulants and processed food. Set a clear, honest intention. Limit media, social media, and content that creates unnecessary noise in the nervous system. Arrive rested, ideally a day or two before the first ceremony. Communicate openly with your facilitator about everything relevant to your health and your history.
