Does anyone know what to take?

Lately my nose has been stuffy from time to time.. and when I tilt my head back, I feel a little drip, but not too much.. my throat isn't sore.. however, my mouth is producing a lot of saliva, almost making me sick when I swallow it.. I'm thinking it's my sinus.. does anyone know a med for this?... Ginger ale seems to dry it up sometimes
