I too wish to describe certain symptoms and seek advice as to whether it would qualify as GERD or related to GERD in any way:

I have recently begun taking several medications and find that I have an accumulation of "thickened-saliva" at the back of my throat. I think it is too thin to be described as 'mucous' but it is a clearly detectable accumulation of an unpleasant tasting substance that does not appear to be stomach acid since it does not "burn".

The meds are:
insulin
lopressor
warfarin
diltiazer.
