That 4 PM coffee may clock out long after you do. Before buying another sleep gadget, check the timestamp on your last caffeine.

🚪 Today’s simple move

  • Write down when your last coffee, tea or energy drink happens.

  • Move that serving earlier, or try a caffeine-free alternative.

  • Keep bedtime reasonably consistent while you notice the difference.

⚡ Try this

• Check tea and soda too
• Change one habit at a time
• Keep a simple sleep note
• Make the evening quieter

Timing is the experiment.

No universal cutoff works for everyone.
