Long shifts wreck people who guess their energy. Caffeine too late. No food in the middle. Wind-down that starts after you already get home.

Stay Functional Through the Shift is a three-zone system for nurses, warehouse staff, drivers, security, and overnight workers who need alertness now and protected sleep later.

What you get

• Pre-shift, mid-shift, and post-shift decision zones

• A green / yellow / red caffeine timing map

• A fatigue triage checklist (hunger, dehydration, monotony vs real sleep pressure)

• A recovery sequence that starts before the shift ends

• A 7-chapter week that holds together instead of collapsing on day 4

This is for you if you work nights, rotating, or 12-hour blocks and you are tired of stimulant chaos.

This is not for you if you want medical advice, or you will not follow a simple timing plan.
