Dry mouth: Sounds like you likely breathe through your mouth at night, causing dryness. The air pushed into the airway by CPAP can make this worse. Drink fluids in the evening to make sure your body has enough water to produce saliva.

Several reasons: There are several reasons this could happen, but with a new start to cpap, would make sure a patient has a humidifier attached to their cpap and also adjust the humidifier settings to assist with this. Other reasons could include diabetes and insufficient fluid intake. A sleep physician or a medical equipment company could help.
