Hi there...sorry you had to come here but glad you found it and have a great doc!
I hope they get clear margins for you and you can heal without having to have adjunctive therapy(rad and chemo).
Glad you also have a good support system...but you need to be ok with letting others help you when you need it, and don't beat yourself up if you can't do some things for a while. Think of it as a not so fun vacation,

As for dry mouth...I tried humidifier by my bed and the spray bottle, and none really did anything. So now I just use dry mouth mouthwash before bed and when I get up. I still wake up with a very dry mouth, but it's manageable.
Will keep you in my thoughts and hope for a swift recovery and clear margins!
