Thanks for letting me join this group. I belong to two other groups on F.B. it’s been a life saver for me to communicate with others. I started CPAP therapy 23 days ago and have used every night. My AHI varies from 1.1 to 2.4. Last night it was 2.4 with 12 clear airways and no obstructive. Should I be worried? Secondly, I’m not sleeping through the night. Is that common?
