My doctor says that my nose is totally blocked on one side from a deviated septum. Does that mean I can use a full face mask, but can use a nasal mask?
With a deviated septum, you are likely breathing through your mouth due to your nasal passage being blocked. A full face mask will certainly work for you and would allow you the option of breathing through you nose and/or mouth. If your mouth is dry in the morning, you are probably breathing through your mouth.
