I've had mine for about 7 or 8 years. Had nasal and throat surgery , and it helped for about 2 years. Was told later that it was a temporary fix. I can't sleep without mine now. Mine is the nose type, as the nasal pillows did not work. My neighbor hated his cpap and would not use it. He died in his sleep from it according to the doctors. He was 63 years young. Im afraid not to use mine now. I'm thinking about the mouthpiece and trying it. Good luck all and sleep tight.
