I started taping and it has helped some, but once I'm deeply asleep and relaxed, my mouth still drops on the inside and the tongue with it blocking my breathing. I'm wondering what else I can try. I'm thinking of some type of oral appliance along with the CPAP that will not allow my lower teeth to fall and that will also keep my tongue from falling back. There are so many! I tried a TapPap nasal pillows but it only has the upper tray so my lower jaw would still fall and allow air to escape. Has anyone had success with an appliance that will keep your mouth closed, not allow you to breathe through your mouth, and keep your tongue in place - either with or without the CPAP nasal or nasal pillows mask? Thanks.
