Man is it making a difference.
I came in and took about 1 1/2 nap very early, then went to bed at 10:30 – 11:00 and slept all night.
The mask did not wake me up either time, which is a huge improvement. I was waking up and adjusting the other mask nightly, which doesn’t seem like a good thing to me. Doesn’t seem to bother the doctor, but oh well….
Worth every penny…
