Need support with new oral appliance

I just started using my somnodent last night and I'm very worried about my future compliance. I have low moderate osa and using a combo of posture adjustment and acupuncture was beginning to feel like I was getting decent sleep. I was trying out this method while waiting for the somnodent to be made. Yesterday I used the somnodent for the first time, but was only able to leave it in for a few hours before being woken up with pain. Then for the rest of the night I had significantly worse sleep then in previous days and woke up within palpitations and a bit dizzy. How do I persevere with the oral appliance when it seems it will have a negative impact on sleep in the short term?

I should note I was treated by a highly experienced sleep dentist who has been fitting OAs for 15 years.

Have you discussed this with him? He/she probably needs to know if you are having issues and what those issues are. Just as with CPAP machines and masks, there is a learning curve AND it takes time to get used to the whole thing--how it fits, not being used to something on your face or in your mouth while you sleep, is it working? That short term negative impact is not easy to get past but once you speak with your doctor on the issues, it's a matter of persevering. Let us know how you get along.

I am a dentist working in dental sleep medicine. In terms of advice, Ruby got it just right. Arthur B.Luisi, Jr., D.M.D.

I'm getting it modified to be a bit looser. Will let you guys know how it goes, thanks!
