That sounds like central sleep apnea - you should get a sleep test and find out. It could make a huge difference.
The problem is, it has been like this my whole life, one thing though, you can NOT wake me up when I am sleeping, I won’t wake up, when I go down it is for 3-4 hours no matter what, I used to sleep walk as a kid. I just chalk it up being born with Gods gift to Humanity that was never stifled with mood altering drugs administered by the State, ADD and HDD
