Many untreated and/or undiagnosed apneic individuals sleep longer because their sleep is fragmented and non-restorative.
Get a sleep study, my good FRiends! Keep your precious cognitive abilities and memory.
Sleep apnea is treatable without drugs, and the cpap/apap is much easier to adapt to than some claim.
My sleep is fragmented because of having to go pee every 90 minutes or sometimes 3 hours. And sometimes stay awake for 1.5 hours. So maybe nine hours sleep over 11 hours or so. No prostate problem nor metabolic syndrome. And oxygen sat looks fine. Lots of supplements for all kinds of things.
