I learned about using easy-to-remove tape to eliminate nocturnal mouth breathing in an interview with James Nestor on Youtube. Read his book Breath for more information. To prevent mouth breathing, place a small strip (I cut a 1" x 1/2" strip off the roll) to keep your lips gently closed while you sleep at night. I've been using the method for a week and it definitely improves nasal breathing. 3M Kind Removal Tape is inexpensive and functional for this purpose. There are other products designed and intended for this use, but I find this simple reel to be easy to use, effective and economical.
