I took Guaifenesin in pill form, huge horse pills, and was on Salagen and I believe both helped but still had thick phlgem.

I think it was my RO that told me this and can't remember which one set is which. We have two sets of major saliva glands, submandible under front of chin and the supramandible up by the ears. While they both make saliva, one set of these sets is responsible for making the thin stuff that thins out our saliva and the other makes the thick stuff. It's when the thinning set stops working that we get this yucky thick stuff that gags us. Since I had XRT for an unknown primary, it's a wonder that anything still works. I can only attribute it to the meds I was on.

I thought you might put that tidbit into your research project.

Take care,
Eileen
