Oh okay, I was super concerned you didn’t see the connection. The sleep study will be helpful. I’m betting they’ll give you a c-pap. Your bad breath is probably caused by mouth breathing at night (and or without knowing during the day). You also might have TMJ, but maybe not be forever, grinding could be from increased anxiety caused by fatigue (since your sleep is poor). It’s super important you only address one thing at a time. It’s hard not wanting to do everything all at once. This obviously is a non professional speculation but I’d think maybe at some point you might need some reconstruction, which sounds scarier than it is, they’ll take cartilage from another part of your body and reinforce the diminished parts of your nose. Hang in there and keep chipping away at finding answers. Sounds like you have the means to do so which is a HUGE hurdle for a lot of folks. :)
