Unfortunately, from my reading over at apneaboard.com, some people never do get out of the 'brain fog'. Even with tweaked machines doing really well for their owners, the owners swear they're almost worse off than they were prior to commencing their treatment. I am not one of those.....but...I can't tell you how surprised I was to learn I had sleep apnea. No, SEVERE...sleep apnea. I was shocked. I slept well, reliably. I didn't sleep long, maybe 5.5-6.5 hrs each night, but it was solid, and I dreamt. Fortunately, things didn't go south when I commenced my treatment.

I feel for people like you who can't seem to get out from under the apparent deficit. You will have to convince yourself that you're getting long-enough sleep, and that the quality is good. Your morning AHI record must become part of your self-assurance that you are breathing well and getting rest.

And to that effect...................................................................................................................IS...your morning AHI less than about 3.0? If it is 4. 6, or higher, you're getting too many hourly arousals and/or obstructions. Remember, the AHI stands for 'apnea/hypopnea index.' You may not be getting many/too many apnea events, but if you have 'UARS' or some other disorder (upper airway resistance syndrome), and you struggle to breath freely, your heart is still coping, and so is your brain that desperately needs better sleep. You need to know your morning's AHI number about the previous night's sleep.
