Caffeine Cutoff Protocol

Caffeine has a half-life of 5–6 hours. That means a 2pm coffee still has 50% of its caffeine in your blood at 8pm. This protocol structures your caffeine intake so it fuels your morning without wrecking your night. Simple rules, massive impact on sleep quality.

Overview

This protocol turns a broad sleep goal into a repeatable sequence. The point is not to add complexity; it is to make the behavior easy to run the same way every time, then let the consistency compound.

Expected benefit

10–20% increase in deep sleep within the first week. Faster sleep onset. More consistent energy throughout the day without the afternoon crash.

How to think about it

Run it as written for the first block, then adjust one variable at a time. The useful signal comes from repeating the same inputs long enough to see what actually changes.
