Hello, I was just diagnosed with sever sleep apnea about a week ago. I used my CPAP machine twice so far and have felt a slight difference in how I feel during the day....not exhausted. I have to use a chin strap with my machine and my question is this....are there any tricks that anyone has on how to keep that chin strap on my head during the night. I have far more trouble with that than with getting used to the machine. Any help anyone could give me would be greatly appreciated.
