I think the many apnea events were triggering the body to “wake up.”
Once awake, any feeling of the need to urinate was registering in the brain, so, off to the bathroom (repeated however many times nightly). Logical to think that waking up was the result of needing to urinate (and not from apnea events).
With CPAP, the person sleeps through soundly (few apnea events) and NOT waking up frequently. Normal bathroom trip in the morning after waking and getting up for the day.
That’s been my experience.
I didn’t read down far enough to see your post, Skybird.
Isn’t it a wonderful luxury to be sleeping?
I count it as a blessing during my prayers.
In the morning, I absolutely relish knowing I’ve slept through the night.
