Tonight
Tape your mouth shut while sleeping.
Sounds odd. Many people notice a difference within a few nights. Use a gentle skin-safe surgical tape — the $4 pharmacy kind works as well as the branded “mouth tape”.

This week
4–7–8 breath, 3×/day.
4 in through the nose, 7 hold, 8 out through the mouth. Takes 90 seconds. Best before meals, before bed, and after stress.

Stop
Coffee after 14:00.
Caffeine's half-life is ~6 hours. It's still in your system when you “fall asleep but wake at 3am wired”. Switch to decaf if you need the ritual.
↓ Deep dive — why this works
Your nose isn't a backup airway. It's the main one.
The single biggest sleep variable most people never check is how they breathe at night. Mouth breathers dry out their airways, snore more, and often wake up unrefreshed — which explains the "I sleep 8 hours but feel exhausted" pattern.
Nasal breathing produces nitric oxide in the sinuses, which widens the lower airways and helps your blood take up oxygen more efficiently than mouth breathing. It's well-established respiratory physiology — it just never made it out of the journals and onto your nightstand. It's also the simplest, cheapest intervention in the whole Blueprint.
