Thank you so much for considering my problem. About the drooling, i can control my mouth to close tight enough to avoid it. This saliva production don't really happen while im asleep. It starts to produce when my first consciousness opens in the morning. And so I cannot go back to sleep because I could already feel my mouth soaking. And this horrifyingly happens every morning of my life.
And, maybe I can try the antihistamines. Thank you so much.
Are you just concerned about drooling? You are a side sleeper and you have drool on your pillow in the morning? This is nothing to be upset about Just put a cover on your pillow that is washable. One that also contains dust mites would take care of dust issues at the same time.
It is very easy to dry the mouth. The reason people say brush your teeth is that the sodium in toothpaste is drying. But your teeth don't like a dry mouth anyway.
