SleepShift Mastery is a practical sleep system for people whose wake time changes every few days. You will not get a 10pm bedtime lecture. You will get a repeatable way to plan the next sleep window around the next required wake time.

Inside the guide:

• Set a sleep window from the next clock-in, not from a fake “normal” bedtime
• Treat light, caffeine, meals, and bedroom entry as one sequence, not four separate habits
• Handle early starts, overnight finishes, isolated days off, and quick returns
• Run a 14-day test so you can see which timing problem is actually costing you sleep
