Even though you are using a full face mask, you may be mouth breathing. That won't affect your therapy much, but can cause dry mouth. Another thing to try is turn up your humidity setting.
Some things to do:
Order the Clinicians manual for your machine (have exact name and model when ordering).

Down the free
OSCAR software.

Also, be sure there is an SD card in the Cpap while sleeping.
Once you've done all that and you have a couple days data on the SD card, start using the software to track your therapy and post a couple days charts here.
