Did you know it isn't excessive salvia, but the inability to swallow properly
 

Excessive Salivation

Rather than an over production of saliva, excessive salivation (or drooling) is likely the result of an accumulation of saliva in the mouth due to less frequent swallowing. Feedback therapies along with speech therapy to encourage more frequent swallowing of the saliva is often helpful. If the drooling becomes severe, drops of ophthalmic solutions of atropine under the tongue are helpful.

My poor pillow...makes it hard to go back to sleep when you awaken and the pillow is wet...bummer!

This was yet another topic in a presentation at the PDF 50th.

I just read about this a few days ago. I dribble too, and not just at night. I reached down to tie my shoe and drooled all over it.
