Depending of your problem you will some benefits of using the CPAP device, also you will havent snoring. Try it before buy it, i believe that your representive companies around you can offer this.
hi CalmAmethystAardvark9591, my suggestion on your problem, is first adjust better your mask so you will not have leaks, where the leaks could lead to feel the air colder, and then if you fit the mask better and will have same issues then try heated tube with humifier.
but i can suggest you to see another full face mask, i have tried many time this mask and its not so stable and could produce leaks and the leaks lead to your problem, check from the device that the leaks doesnt exceed the 24l/min, the pressure you have its very high and even this can dry your mouth.
Hello SleepyScott, its little late answer for you and hope you have found a solution on your problem,
By using the Full face it doesnt mean you need change any of the settings in your device, but maybe due of the size of the mask, due that is heavier and maybe you just feel like this. also you need to check for the leaks because with full face mask its easier to have leaks and maybe the leaks produce leak voice which maybe disturbing your deep sleep.
