3. Review before changing the plan again

Discuss persistent symptoms with a clinician or mental-health professional. Use the review to test whether persistent insomnia and severe daytime sleepiness deserve assessment. If the picture is still unclear, improve consistency or allow a more suitable observation period rather than changing several variables at once.
