Anyone sleep with CPAP therapy?

Girlfriend wears one , used to have just a device in the mouth(like dendure prothese)to keep mouth open and ease breathing , the effect of tht wore off so now she has cpap and I agree If you have health insurance they want to tap into the well . Must say it helps my sleep alot because when she forgets it or just rips it off in her sleep , the snoring starts (freight train)!
