I have been using this mouth tape for about 3 months (or more) & I absolutely see a difference not only in my sleep, but my FACE! It’s so true, it snatches the jaw. The difference is insane. Absolutely love and I have told everyone about it. After about 2 months I got my husband on it & he also loves! Couldn’t recommend more. First pic (in the khaki jacket) was in November right before I started using it. Picture on the right was taken in February. Just to preface, I haven’t lost any weight at all- simply a change in SLEEPING IN MY MOUTH TAPE!
