Same; got a study after having a really bad bout of headaches and mood swings. I was suffocating in my sleep with 60AHI. Anything above 5 is apnea, above 30 is severe. From what I understand, apnea is insidious because it develops slowly and your body acclimates to your increasing CO2 levels, even though the lack of oxygen is causing brain damage. Getting ASV therapy has been a game-changer. I was turning into a cranky dumb brute and ASV started reversing it, once I acclimated to therapy. That took about 4 months though.
