I have, and like you said, getting one is s nightmare.You should look into getting a CPAP machine, although the process to get one is the biggest load of doggie crap in the medical insurance industry.I had nothing but sinus issues and snored like a chainsaw for 45 years. No woman would sleep in the same bed for fear of being beat up by my flailing about. The machine is truly a PITA especially if traveling, but it fixed my sinus issues and I sleep soundly now, my two cents.
