I tried mouth tape out of desperation bc I sleep so poorly. I didn’t realize that every morning I woke up with a sore throat, until I used this tape and no longer have a sore throat. I do not sleep better, longer, I do not have a new jaw shape, but I do wake up without a sore throat, and that’s enough for me. I won’t sleep without the tape now. Even my kids know “mom needs her mouth tape.” I love that it doesn’t cover my whole mouth too! Thank you Vio!!
