I thought I would update you all on what happened. I finally got into my sleep medicine doctor and he said that the medical supplies company which is associated with my doctor's company told me wrong. My prescription had not expired and was good until November. He showed me on the computer my records. I thus saw my doctor months early. The medical supplies also told me that my CPAP machine was broadcasting my results so I did not need to bring it in. The doctor did not have any records so now I would need to make another appointment to see how I have been doing these last months. The problems of life. I did get another of my old mask and seem to be doing better with it.
