I will be having a bridge on my upper teeth. Is this a problem? The problem with all the different sleep masks has been the noise which wakes both my wife and me up during the night. And it is uncomfortable. I often take it off in the middle of the night so I can finally get some sound sleep. On the other hand, when all goes well(which it did during the first three months, when the machine was "officially" mine,) I was just fine, and my wife happy. She wants me to try again, and I just refuse.
I find that charging me for an answer is false advertising, as it is said to they if for free.
