here is my last night screen :

based on the dr Krakow's analysis, i'm thinking maybe i also have UARS, because of my throat inflammation, this is how it looks like almost(image from google):

also i woke up at 7am, stayed awake till 9:45am then slept from 9:45 till 11am, and i noticed this maybe the explanation what is happening: before i dose off, almost dreaming, so i'm between awake and asleep still but i am dreaming already, for less then a second, i hear my throat "noise" it is not snoring but noise, and i feel i'm trying to inhale as if i am trying to breath from a straw, it was hard and in that split second i wake up, and my throat opens and i am breathing normal. so i know it happens in that time frame, i tried to zoom in looking for it in the graphs, but i can't tell exactely where i woke up in this hour and 15 mn, so i'm highlighting these maybe you can see something i am not. i can only see that in the inhale curve, there is some jagginess, or little flatness before the curve goes up, maybe that is that ?

and

Also took some random zooms in the normal night sleep where i saw some abnormalities :






Now what should i do ? do i need lower more constant pressure as CPAP ? do i need higher pressure to combat that narrow airway? also it always seem to wake me in REM, it might be happening more often but i remember the wake ups when i am dreaming always.
I'm sure i'm not getting enough deep sleep as i also wake up almost fully awake each time i wake up through the night.
In my sleep study my sleep efficiency was 60%
in 5.35 hrs of sleep i had : 122 arousals , 69 associated with apnea/hypopnea and 35 RERAS and delayed onset REM. total AHI: 17/hr and RDI was 23/hr.
