Anybody know good remedies for a chronically stuffy nose? When I'm up walking around during the day, I breathe fine. But the second I lay down, my nostrils decide it's a good idea to close up. Even if I liberally use saline nasal spray, they get a little dried out during the night too, which doesn't help. I need to find a way to fix this problem, because I haven't worn my CPAP mask in three nights now because I can't breathe with it on because of my stuffy nose, and I'm starting to feel the effects. I have a medicated nasal spray, but I'm not using it anymore and I haven't used it in two weeks at least, if not longer because it messes with my heart and makes it beat all fast. I want to breathe again!!
