At night, separate a thought that needs a daytime decision from a thought that is asking for certainty you cannot produce in bed. A brief note can preserve the task without turning the night into another planning session.

A worked situation: Tomorrow's meeting may go badly

Fictional example. An employee mentally rehearses tomorrow's meeting. She writes one question to ask at 9 a.m. and stops editing an imaginary conversation. The note is an organizational option, not insomnia treatment.

Work through these questions: Tomorrow's meeting may go badly

Question or fieldFictional completed example
Thought?Tomorrow's meeting may go badly
Actionable detail?Ask which decision is needed
Daytime appointment?9 a.m. planning window
What is unknowable now?Everyone's reaction
Stopping point?One note, no more rehearsals

Close an actionable loop before bedtime

If a thought contains a real task, write that task and a daytime appointment to address it. If it asks for an unavailable judgment such as what everyone privately thinks, label the uncertainty rather than inventing an answer. The record ends when the next action is clear; it is not an instruction to keep analyzing until sleep arrives or a treatment for insomnia.
