This was my first in person visit with my sleep doctor. I waited over 8 months to get a video visit and a sleep test. I obtained my CPAP four months ago and finally had an in person appointment. I'm very happy with the CPAP results but wish it hadn't taken over a year to accomplish .

This doctor didn't listen at all. He completely disregarded everything I told him. All the treatments he wants me to do I had already told him I'd done and they didn't work.
