What Causes Dry Mouth? -- this question was asked elsewhere by Edwin Scott; reposting here in its proper location: "Lately I've been waking up with a dry mouth. Does anyone know what causes this?"

Edwin -- dry mouth is usually an indication of mouth breathing -- opening up your mouth at night and breathing through it instead of/ in addition to your nose. If you're wearing a CPAP mask, this will cause the positive airway pressure to fail by escaping through the mouth, instead of being used to splint open the airway as intended.
