14 years post treatment and very grateful to be cancer free I do struggle with some post radiation issues. Dry mouth was low on the list until recently. Not sure why but it got bad recently during sleep. Like waking up 100% dry. Very bad for teeth. I came across a product designed for snoring and (even though I don't snore) I decided to try it. It has helped me SO much. It's a special kind of tape called Adellina Premium Tape. Like $17 on Amazon for 30 patches. Right before bed I just peel a piece off and put it on my closed mouth. I can't even tell it's there and I sleep all night breathing through my nose. Zero dry mouth. In the morning it comes off with no pain or even discomfort. I hope this helps someone. The OCF saved my life 14 years ago.

Peace
