This sounds just like what I experience just about every day and night. I wake up sometimes gaging and coughing and it is so thick I choke and throw up some. I have tried all the sprays and rinses and nothing seems to work permit. So I feel I am tied to all these things just to breath. I am just starting to take mucinex tablets at night along with a good saline rinse and budesonide. I can't believe the medical field can't find a fix for this.
