I started using the machine a couple months ago. At the same time I developed a mouth ulcer. I was given a mouth rinse that I discontinued use after sensory issues to it. I have strugg With this issue and the dry mouth from the machine. Could they be related ? I wake up every morning with sore lips ...

I’ve men using the machine for 2 months now. Wondering if everyone actually replaces hoses and headgear every 3 months as suggested? Seems like this is a lot of money to have to spend every 3 months!
