Nighttime and overnight participant support

The manuals converge on the need for overnight participant support to be calm, structured, and safety focused. Across the extracts, overnight stays are used to maintain observation after dosing or experimental sessions, with attention to comfort, safety, and timely escalation if distress or other needs arise. They also agree that support is practical and present, including companionship, quiet presence, and monitoring until the morning or next-day integrative session. The sources differ in how much operational detail they give. The PTSD manual emphasises staying overnight at the clinic, offering food and liquids, recognising distress, and arranging safe transportation home after the session. The MAPP2 materials place more emphasis on periodic check-ins, minimal supportive contact that is not intrusive, and orienting attendants or support persons to confidentiality and emergency procedures. The MP16 synopsis adds coordination language, including trained attendants, instructions for contacting the therapy team or physician during the night, and deciding whether a participant remains on site, returns home, or needs additional observation.
