Hi Doc,
What does it mean when you wake up in the morning with a sticky substance in mouth?
In the context when you have chronic sleep problems(agitated sleep,you do not feel refreshed afetr waking up,somtimes nervous) and have deviated septum
It's probably either from dryness due to mouth breathing, or from your stomach juices that are being suctioned into your mouth. I would consider seeing a sleep doctor about possible sleep problems.
