I Don't Know How Much Longer I Can Do This

Thank you to all of you for your replies! I learned more here than my last 4 visits to my sleep clinic.

I went and looked at machines today and called my health care insurance provider. (I am covered 80%) The tech at the place that sells the machines was very helpful. With your advice and her information I think I have a good start on choosing a machine. Even if my health care insurance provider will only pay a certain amount I am willing to pay anything over and above as it seems a really good machine is essential.
Thank you again. I will be back!
