Amazing - Last night, I slept w/ the oral device that a got from a dentist a number of years ago - fully paid for by insurance.
This dentist specializes in providing them to his patients. I had stopped using the oral device because I would bite the inside of my cheeks and lips. The dentist didnt seem that interested in adjusting it. His assistant told me to be careful when I was eating/chewing - DUH.

Since I stopped using it and refused to go back to the C-RAP, I began taping my mouth shut. It has worked and it didnt bother me if I was really tired, like up past my normal 2 am bedtime. If not really tired, it will bother me a bit but NOT as bad as the C-RAP.
Last night, I decided to give the oral appliance a try again w/ just a small amount of tape on my mouth to keep from chronic mouth breathing when sleeping.

After 7 hrs and 57 minutes sleeping, the Snorelab app I use showed a Snore Score of 0 or 1% of 7 hrs and 57 minutes. From the info on the Snorelab app, I could see there was one event where I snored for 20 seconds but during that time - w/ one exception- all of the snoring that occurred during the 20 secs was at less than 10 second intervals - mainly 4 second intervals. For the exception, the interval was 11 seconds between snores.
From a number of websites and conversation w/ a tech person who analyzes overnight hospital sleep studies, that an apnea is defined as no breathing for more than 10 seconds. Per Johns Hopkins:
"Obstructive sleep apnea occurs when your breathing is interrupted during sleep, for longer than 10 seconds at least 5 times per hour (on average) throughout your sleep period. "
I posted a link to the Johns Hopkins site but new members not allowed to post links so had to delete it. I found the info gooling it.
Probably tomorrow my Sleep Score will be 64! If you have any questions, please ask and I will try to help w/ answers. I know how horrible it can be to use the C-RAP, rip off skin when taking off the wrong type of tape, feeling claustraphobic w/ mask or tape on and wasting money on things that didnt work. Carole
