I love my CPAP. I am more rested with it. It took some adjustment though. Mine was set to turn off if it didn't detect breathing after thirty seconds or something like that. Sometimes I would mouth breathe and since the mask is on my nose it wouldn't detect it and I would wake up in the middle of the night and it would be off. I called the resp therapist and she showed me how to reprogram it so it would not auto shut off. Now the only time it shuts off when I am sleeping is when my cat walks across it and her foot presses the on/off button.
