@ccbwell something else that has really been helping is something called AlkaLife pH Booster Drops. Try to get your water that you drink to 9.5 pH (it may help to test with a pH meter - This one's super cheap and at least will get you in the right range. https://www.amazon.com/gp/aw/d/B0FKYB2R92) Apparently 9.5 pH water immediately denatures pepsin on contact which keeps it from irritating your throat as much, even if you do have silent reflux.
I have a bunch of big yetis that I just keep it in and drink from all day long so it's constantly helping.

I also found this blog by the supposed world expert on respiratory reflux. You can read through her blog on her website here and see if anything resonates. https://jamiekoufman.com/

since implementing some of the things she talks about, including the water and the alginate (reflux gourmet) I have stopped the twice a day Mucinex and all the asthma medicine (advair and spireva) that my pulmonologist prescribed me and feel much better.

Hope you find some relief soon!
