Hi ya'll I'm Rick, 67 years old and have had a bipap for about 9 months. No success. I wake up with a very dry mouth, not mouth breathing, lips are stuck together. When I get up, I start sneezing, coughing, and have a continues post nasal drip, none of which I had bipap prior. Any ideas? I'm not to be compliant if this goes on. Thanks for any ideas.
