Hi Beth, I cant imagine having to sleep with one of those 
...I was wondering if perhaps the mask is what your having a problem with? Can you take the machine to have it refitted or looked at in this way?
Other than that I dont have any ideas Hopefully, someone will come along with somemore for you. Please do keep posting and let us know how your doing. Take care
