so how did it go?

The liner for the face mask work good, I use the quattro fx for women and with the liners I dont have any leaks.
The liners do take some adjustment to be comfortable but do stop leaks for me.

I started using my machine in March of 2012 and I am just starting to really feel a difference in how I feel. I still get tired by the afternoon but not feeling like I am in a fog all day.
I think you better discuss your issue with your sleep doctor.
