I read through most of this thread. I didn't see anything that mentioned why I was drowning in
saliva/mucus so I thought I'd mention it, in case someone might benefit. The doctors said it was Gerd. I had an allergy skin test and discovered I have all-season hay fever. I was allergic to everything on the panel except two things. I ended up having 5 years of immunotherapy therapy allergy shots. The most common hay fever symptoms are red itchy swollen eyes and runny nose. I never had these symptoms just tons of saliva/mucus.
