However, a couple of weeks ago, I have realised that I have been experiencing
post nasal drip. I am not sure if it is caused by the dry mouth, or if the dry mouth is causing it. Regardless, if I don't swallow frequently, mucus builds up at the back of my throat. I cannot seem to spit it out, and I have to swallow it.
Also, if I talk for too long, or go without drinking water for too long, my tongue dries up.
