It's normal to have 3 to 4 % drops in oxygen levels during sleep and those alone don't mean much.
It's also normal to have a spike drop to a lower level just from loss of contact so I don't worry too much about the minimum being reported without seeing how long it might have stayed at a lower point. Like that 91%...were you there for 1 minute or 10 minute kind of thing.

The sleep endoscopy thing...that might be what we call a sleep study with Pes device which would be useful to find out if you maybe have UARS or not...Upper Airway Resistance Syndrome.
Treatment is still the same...cpap but you might need more pressure to help resolve it than the machine in auto adjusting mode will want to give you. With UARS people don't have marked oxygen level changes beyond normal variances but they do have crappy sleep.
The data that our machines gather isn't always that helpful because it isn't designed to look for the minute changes that UARS presents in the flow rate. Sometimes flow limitations are a helpful data point but not always.

Here's the distribution of total minutes at each SPO2 level last night. Maybe not that bad?

Any thoughts about whether this is a worthwhile avenue to investigate further for possible correlation with crappy sleep? This device doesn't sync with OSCAR but just eyeballing the graphs on the app it comes with I don't see an immediate correlation with flow limitations. I know this is just one data point.

Thanks so much!

as you say, one data point. i don't pretend to know much, but i do know that in most cases, it takes awhile for the body to adjust to these kinds of things. so give it a few nights to let yourself get used to it.

meanwhile, good work! this twice now today where i see users with improvements.

A couple of things come to my mind reviewing this thread.

The need for frequent and copious urination is unlikely to have anything to do with your PAP settings, so if that persists, I would recommend that you follow up with your doctor. Be sure to describe your symptoms completely, e.g., daytime vs night-time; fluid intake, what , how much, and when; number of days you've had the symptom.

You might also want to review your meds with your doctor. Here is what I see on line by way of more common side effects:

Gabapentin: Drowsiness, dizziness, loss of coordination, tiredness, blurred/double vision, unusual eye movements, or shaking (tremor) may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Lunesta:
• day-time drowsiness, dizziness, "hangover" feeling;
• headache, anxiety;
• dry mouth;
• unusual or unpleasant taste in your mouth;
• rash; or
• cold or flu symptoms such as fever, body aches, sore throat, cough, runny or stuffy nose.
Tizanidine: bradycardia, dizziness, drowsiness, hypotension, asthenia, fatigue, and xerostomia. Other side effects include: constipation, and increased liver enzymes.

Finally, I notice that on the charts you've posted, you haven't clocked 8 hours. Do you try but find you can't get back to sleep? Or would you benefit from planning for more time to try to get in more sleep? People's need for sleep can be very different from person to person and, for the same person, over time.

Thanks. My copious urination has subsided fortunately - still wake 3-4 times a night but always have for the past 10 years. The gabapentin and tizanidine are fairly new but I've had these issues prior to starting those. Been on lunesta for several years and have tried tapering off but rebound is hell.

And regarding amount of sleep, I've never in my life slept 8 hours, even if I try. 7 hours is a dream of mine. 5-6 is typical. I would say that's all my body needs if I didn't feel like shit all the time.
