I am 18 years old. I always have translucent, bad smelling saliva formed in my mouth while waking up. It starts forming if I sleep even for an hour and re-accumulates after spitting. It smells very bad...Many a times I even have to wake up in the middle of the night as the liquid fills my mouth. It stops forming only after I brush my teeth in the the morning. It has been almost 9 years since I am facing this problem.

I am very eager to know about the reason behind this problem and its remedy. PLEASE HELP ME OUT!..
