Hello. My name is Diana. I was diagnosed with OSA and have been using a c pap for about a year. I had a hard time getting used to it and almost GAVE up. They worked with me and thank heavens I got used to it and wear it now every night.I had been falling to sleep eating lunch, and using the computer, or watching TV. Really at the drop of a hat. I finally got to the point that I had two traffic accidents and had to quit driving altogether. Now I feel so much better,I finally started driving again.I am thankful that they were patient and help me so much.
