I use a cpap for a number of years but frequently woke up in tremor unable TO BREATH THE FEAR WAS strong I would often rip the mask off and toss it across the room. I also tried a custom mouthpiece made by a dentist that was supposes to help align your mouth and jaws as to keep my airway open that was pure torture. I understand the issue but so far, the ‘cures’ have been as bad as the problem!
