Anyone sleep with CPAP therapy?

I use one!
In fact, I'm past a CPAP and use a BiPAP. 19cm.
I don't mind telling you it has made a huge difference in my life too.
As for whether I need it or not, the VA did the study and signed off on the BiPAP.
The VA is a bunch of tight wad ****'s, so if I didn't need it, I wouldn't have got it.
I had trouble the 1st few nights, but once I got used to it, it was all good.
In fact, if I don't have it, I don't sleep.
