So far I haven't, nope, though it might be worthwhile to look into, given that I basically need 8+ hours of sleep to function well. I do have a fitness watch though that can (supposedly) measure SpO2, and while that showed the occasional dip, it seemed more like a measurement error, and generally the values were in the normal range.

I've a FitBit Sense 2 and as I understand it that measures variations in SpO2. I'm not convinced how accurate nor how quickly it responds, it derives an estimate rather than directly measuring. I think it's also sensitive to any movements of the watch on your wrist. I also have had a finger pulse oximeter which logs and exports to an app via USB. If I sleep with that on it seems to be very reliable at recording the levels, the data certainly looks good and feels much more reliable than the Sense.

My Apple Watch showed no major desaturations. The desats only last a few seconds.
