I just got the results from my WatchPAT ONE sleep test, and the summary basically says I don't have apnea and points me to a CBT-I provider. Do you think the data points to UARS (due to high RDI/low AHI?) or do you think it mostly rules out breathing issues (too few respiratory disturbances?)?

Context

I've been struggling for years with poor sleep quality and daytime tiredness, but this past year, I've started to feel extremely fatigued from the afternoon through the rest of the day. I've tried supplements like magnesium glycinate and theanine, maximizing daytime light exposure/minimizing nighttime light exposure, strict sleep sleep/wake times, just being chill and not worrying about any of that, but it seems like nothing helps. I think it's physiological/breathing related; last year, I struggled a lot with sleep maintenance insomnia, but I fixed that by trying to sleep on my stomach more. I can't sleep in even if I'm sleep deprived, pretty much always wake up by 6:00am even with a pretty dark room. My sleep onset latency is very low, I feel like I fall asleep within a minute or two every night.
