Does CPAP change or ruin the voice?
In 1998 I began using a CPAP machine at a fairly high air flow rate. I used it religiously up until a few months ago after losing 80 pounds and getting myself in shape.
What I'm wondering is whether or not anyone here knows if using a CPAP machine can "harm" how well I used to sing. There was a time when I could sing very well (and fairly high for a guy).
I'm thinking because of my CPAP use, my high end (and some of my middle range) petered out. Is this possible? If so, is it possible to get it back now that I'm off my CPAP machine?
I appreciate anyone's solid help here.
