Nasal strips

Adhesive strips rely on their own little spring, and they tend to peel up partway through the night. Intake works differently. A pair of medical-grade tabs goes on the outside of the nose, one over each nostril, and a rigid magnetic band clicks onto them and pulls the nostrils open. The lift is clearly stronger than a strip, and the band doesn't go soft after a couple of hours. The band is reusable, so the only thing you throw away each night is the tabs. The starter kit has four band sizes and 30 pairs of tabs, enough to find your size and get through a month before you need refills. It costs more than a box of Breathe Right, and the tabs are a running cost, but it actually stays put and keeps working until morning.
