Not cured, but treated. I'm currently using a BI-PAP machine that's made a world of difference (as long as I keep my beard trimmed). It's just like a CPAP but will use different levels of pressure for inhaling and exhaling to help trigger the body's autonomic responses to breath. In my case the settings are as high as this particular machine will go, i completely forget what the units are now, 13 units for exhaling, 16 for inhaling.
