Sleeptight

So in 2020 i'll have been in CPAP therapy for 25 years! my sleep study was done in my home, completely wired up, including a night vision camera. a bundle of cables were stretched into our spare room where the tech sat and watched me and recorded my Apneos as i slept. Has anyone had therapy for this amount of time and been able to come off the machine? I've lost weight from time to time and noticed the pressure was more intense. i cannot nap without it and if the power goes out there's no sleep for me. I don't like the EPR feature, i need full pressure all the time.
