Thought I'd ask the experts 
After seeing the damage covid did to my cousin's lungs after a moderate 10 days of symptoms, not hospitalised, a few months back (he dips down to 80s in oxygen saturation when side sleeping now) I used a similar Wellue pulse oxymeter ring to record my sleeping.
Well it seems OK on oxygen a little high in the heart rate. I'd expect higher 40s not 53 as it shows sleeping due my size for BPM but I'm on Apixaban (blood thinner, half dose) and Propafen (for heart stability after one of four stents needed after being too close close to explosions caused scarring in my 20s was replaced, it had slipped a bit.
But I feel just like I have apnea which I know from a decade past, this went when I stopped smoking. I'm to tired to exercise most mornings the past month.
By 11am I'm feeling more energy, common with obstructive apnea however that's not evident. By 8pm I'm nodding off for a few minutes now and again watching Netflix.
Any ideas lads? Metabolic problem? But how to diagnose? Thyroid function is normal/good and my haemodynamic tests came back all good last week.
I'm late 40s, 6'6", 292 pounds but unusually broad build so not overweight.
