1. How to Perform the "Shuffle"

The technique is simple, requires no equipment, and can be done entirely in your head while lying in bed:

Pick a Starting Word: Choose a neutral, emotionally flat word with at least 5-6 letters (e.g., "BEDTIME").

The Letter Game: Take the first letter (B). Think of a word beginning with B (e.g., "Bear"), visualize it for a few seconds, then move to the next (e.g., "Banjo", "Box", "Button").

Shift Letters: Once you run out of B-words, move to the second letter (E) and repeat (e.g., "Eagle", "Egg", "Elbow").

The Goal: Most users find they fall asleep before reaching the third or fourth letter of their starting word.
