Hi @kudzu, I have had issues when I first started using my CPAP when it felt harder to breathe and it woke me up. For me I think it had something to do with the pressure being too high and I was able to restart the CPAP so that it went into ramp up mode where the pressure is lower.
It always feels better when I take the CPAP mask off. I'm guessing you like yours about as much as I like mine. I tolerate it because I know it reduces the amount of events I have at night. Have you discussed your symptoms with your sleep medicine doctor or care team? Maybe they can adjust the machine or offer some suggestions.
