OK, so you will laugh,but I have to share this tip for those who use them. I need a chin strap with my model and I could not find one that I could tolerate. SO,I put a panty liner/mini pad over my mouth at night. It hold my mouth shut,catches the slobbers(yes, we all have them),and it does not hurt when you pull it off. It is very comfortable ! Just use un scented if you have sensitive skin! Ok, you can all laugh now,but it works great for me and might help someone else. :thumbup:
