'...I sleep on my side which seems to do ok...'

I don't know how to interpret that statement. What metric are you using to demarcate 'ok' from ' a poor sleep?' Going by how you feel next morning is a mistake, as I learned in November of 2017. When my polysomnography results were placed on the table before me, I was shocked to learn that I had severe sleep apnea. I felt great, except for the two bouts of AF in June and in September. I felt great, but my heart didn't. It was in fight-or-flight response all night long trying to keep me alive. It finally became vexed enough to complain just a tad...with my first bout of AF near the end of a 10 km run.

If you don't mind continuing to engage me here, would you explain about your intolerance to CPAP therapy?
