For a while now I've often felt tired and sleepy even after getting seemingly enough sleep. I also had a frustrating tendency to wake up at night for no apparent reason, then have trouble falling asleep. My partner noted my loud snoring and suggested nasal airway strips (the kind that go on the outside of your nose).

I was skeptical, thinking "How could a little plastic strip have an impact?" and "I'm not overweight, so sleep apnea shouldn't be a concern anyway." I've tried them for ~1 week now.

Positive Results: I seem to fall asleep much more quickly, I don't wake up at night for no reason, my partner reports that my snoring is way quieter, and I feel more consistently well-rested than I have in a while.

Downsides: They cost $0.25 per day. Also, after ~9 hours, the strips start to get itchy and peel off, making it harder to sleep. The solution might be to put one on immediately before going to bed.
