@Sarah hi Sarah its very nice of you to check in with me. I have been using the BIPAP for almost 6 months now and finding it really good. I feel great no more headaches or daytime sleepiness, much more energy than this time last year! I use the nostril pillows P10 Airfit I think its called and a Phillips Dreamstation. The data from the machine is amazing and it means I need a sleep study less often! My AHI is down to about 0-3 on average which is down from 72 when I started therapy a year ago. Incredible technology! Thanks to you and the other members of this forum for your support when I really needed it! How are you doing? I love all your videos! Merry Christmas and hope 2021 is better for everyone! Kind regards, Carolyn
