Alcohol reduction is a high-leverage behavior for sleep quality, energy intake, and long-term health risk.

Overview

Make weeknights alcohol-free by default to improve sleep, reduce calories, and create clearer feedback.

Wellness education and routine support only. Review the evidence, caveats, and interactions before trying this protocol, and ask a clinician when medical conditions, pregnancy, medications, or symptoms are involved.

  3. 3

    Step 3

  4. 4

    Step 4

    Plan exceptions in advance instead of deciding in the moment.
