I have been on CPAP for 2 months. I thought this issue would go away as I got more experience with the machine, but it’s kicking my tail.
I have a resmed N20, fitted by a pro and double checked by me. If I wear it loose I have mask leak, If I wear it tight, I get leak; and anywhere in between, I get leak. Always, and I mean always, it’s good for a couple of hours when I put it on for sleep. It’s in the middle of the night that the problem develops.
