I've been on a CPAP Machine for four months, had the test on the finger , my oxygen was OK, I've had a little improvement but not much, I'm able to keep the mast on all night, I'm still tired when I wake up and sore eyes. When I went to Mobile, Alabama , I sleep just fine without the machine, when I went to Nashville, Tenn. I sleep just fine without the machine, when I went to seattle, Wash. I sleep just fine without the machine, when I come home to Utah, I can't sleep even with the machine. I'm use to the cpap( like I said my oxygen level tested ok., any idea's?
