I wear mine all the time except when i'm eating although my doctor recommended it. I've had it on for a little more than a month and it helps my bite a lot. My jaw moves back more when I open my mouth. I tryed not wearing it once and after about 2 hours the symptoms came back so now I don't leave it off for more than 15 minutes. It's starting to get really annoying though. I have to wear it for another 4 months. I'm looking forward to june.
