Yep, I ended up at the ER at the heart hospital in aFib. Doc told me that apnea got me there and I’ll be back if I don’t do something about it.I'll second everything said here. Every morning I woke up I felt exhausted. Did a sleep study. Averaged 88 "events" an hour. Got a CPAP. Now I average 1 event an hour. Completely changed my life for the better. Possibly even saved my life. I have not slept 1 night without the CPAP since I got it. I have a portable power supply to run the machine at deer camp, when we go 4 wheeling in the Ozark mountains and in case of a power outage.
