Changing EPR is the real deal, wow.
Was stuck at AHI 4-5 with CA's never going below 2 in 7 years of CPAP therapy. Never felt rested or restored, but my doctor was basically leaving me to fend for myself on that front since the AHI numbers were to her satisfaction.
Just wanted to shout out u/midmod4 for suggesting tweaking EPR as something to try, I changed mine from 3 to 2 and was shocked how immediate the impact was. Both AHI and CA's basically halved overnight, from ~4 AHI to ~1.8 and ~2.00 CA to 1.15. It's only been a handful of days so I'm hoping the trend continues, but already I'm recalling dreams and waking up not feeling that heavy-eyed fatigue, both of which are huge for me.
It's crazy that such a simple change can have such huge implications. I'll be testing EPR 2 for another week to see how things go, and then testing EPR 1 to see if things improve further.
Really grateful for this community, this is the most optimistic I've felt about CPAP in my 7 years of usage. I'm glad to have a doctor to check in with but the degree to which I was kind of left on my own to figure things out has been really discouraging.
