Fish, it sounds like everything is going very well, in the right direction for recovery! I still have dry mouth in the morning or when waking up at night. I previously mentioned somewhere, the salivary glands basically shut down when sleeping, even in "Normal" people, so it compounds our already compromised salivary glands. They have Lycra snoring chin straps, which may help, and be used to keep the mouth closed at night to prevent moisture loss through evaporation or just taping the mouth closed, lightly lol. A humidifier you probably already heard about.

Here is one example of the many types of chin straps. Just check with your doctor if it's suitable for you.

All the best, and keep up the good work!
