Questions
When should I have my last coffee?
When sets your last coffee eight hours before your bed window, and your first coffee about an hour after you wake. Both times come from your own bedtime and wake time, so the window is yours, not a general rule of thumb.
Is the afternoon crash caused by coffee?
Sometimes the timing is, and sometimes it is the night before. When shows both: your coffee window, and how far your weekend night slides from your weekday night. If your caffeine timing already looks fine, the plan says so and focuses on the night.
Do I have to give up coffee?
No. The plan does not tell you how much to drink. It gives you a window, from the first cup to the last, built around the wake time you are settling into.
