[CPAP] In need of help interpreting OSCAR data

[tententen]

Hi everyone,
New user here, had heard great things about this board.
I've been struggling with sleep quality for the last while; waking up feeling "drunk", daytime sleepiness, some instances of being woken up by my headgear/mask.

Some info:

• Been using the F&P Brevida for the last 2-3mo, was using F&P Vitera previously (diagnosed in 2020)
  
• Due to being a smaller Asian woman, it has been impossible to find a mask that will fit my facial structure; I tried on every mask in the local stores, and am not in a financial position where I can buy/exchange masks in Canada (plus, many companies allow exchanges only with unopened items, go figure.)
  
• Extremely healthy, I exercise every day, and am taking Buproprion/Wellbutrin SR 100mg + 15mg dexedrine upon waking (6-7am.)
  
• Going off of my tricyclic antidepressant + Buproprion/Wellbutrin improved my sleep, but due to relapse, I am now back on the Buproprion, which can affect REM Sleep.
  
• I am on the waiting list for a polysomnography, for I shouldn't be having CA events, as it seems to be prevalent in people with heart failure/opioid usage
  
• I had orthognatic (double jaw) surgery last year which resolved my OSA, but I am still experiencing apnea symptoms, and note a lot of CA events in my OSCAR data.
  
• The Brevida seems to slip out of my nostrils from time to time but the larger size physically hurts my face, and I've yet to find a CPAP pillow my neck doesn't hate.
  

The last week or so, my sleep quality has taken a dive once more, and I am feeling the "waking up with racing heart/sense of drunkenness" and physical/cognitive inertia that plagued me from November '22 to February '23, and thus I turn to this board for guidance.

I've attached some of the OSCAR charts, and if I need to upload different images, let me know; I followed the posting guide as best as I can.

Thank you in advance
(Note: I am unable to post images until I've made four posts, so I've attached images instead)

What I see are large flow limits (flow limit chart).  Flow limits are apnea just the same as O and H events.  To control Flow limits we use EPR (exhale pressure relief).  You have yours turned off.

I would suggest you try this and see if it helps, you can always go back to your old settings.

Max 7
Min 4
EPR set to full time 
EPR 3

Thank you so much! I’ll try this tonight.
