• Keeping a sleep and wake-time diary as a plain observation record

  A proposed diary format that records lights-out, estimated sleep onset, wake time, rise time and daytime events in the same fields every day, with the time zone and any clock change noted, so that a series can be read weeks later without reinterpretation; it is a personal observation record, not a medical tool, and it gives no advice.
