Wish I could tell you success from me but I suffer from same problem.

I can get so much saliva and phelm in my throat and bronchial tubes that I cough so much it starts to bother my throat and bronchial tubes and thus cough more.

A long time ago I stopped eating dairy. This seemed to help.

Recently I went on Nutrisystem to lose weight and noticed the saliva and phelm was greatly improved. Not sure why but makes me think I was eating something to cause the irritation thus the excess salvia and phelm.

Maybe check the foods you eat. Do you eat spicy foods? Spicy foods are a known cause for extra salvia and phelm. I know dairy was mentioned to me by ENT as a known cause of congestion and I was having a lot of sinus congestion that was draining down my throat.

Wish I could give you the answer you want but I did want to pass on the marked improvement in the saliva and phelm being produced when I eat as soon as I went on Nutrisystem. Not recommending Nutrisystem just that food maybe a cause.
