Apparently it takes 4 days to recover from losing just 1 hour of sleep. So if you’ve been sleeping with your mouth open for the last 10 years, running on caffeine, waking up feeling like garbage every single morning... You’re basically never catching up. Your body can’t recover when your mouth falls open at night. You’re not getting deep sleep. You’re not restoring. You’re just surviving until the alarm goes off and doing it all over again. One strip of tape keeps your mouth closed so your nose can actually do its job. People who try it for 3 nights almost never go back. Stop digging the hole. Start actually recovering. $.66 cents a night. Beard-friendly. Stays on all night. Or your money back.
