I am not a physician, but I do have personal experience with sleep apnea, and have successfully treated my own symptoms without CPAP. Having said that, I understand that CPAP is considered the "gold standard" in treatment options, so I think you should first be sure that all adjustments have been made in a sleep lab to ensure that the unit has not fallen out of proper adjustment. Have you spoken to your physician about this and if so, what was the reply?
If you have no other alternative but to try something else, and your apneas are obstructive rather than central, intra-oral appliances would be the next step. I have been diagnosed with severe OSA and due to economic limitations at the time, created an intra- oral device that has reduced my apneas from 54 per hour down to 3 per hour and maintains my oxygen at 95%..the same as when I am awake.
