I experienced it with Amitriptyline (worsening of Sicca) and Duloxetine/Cymbalta which dried my saliva ducts up significantly. Since coming off most medications I'm left with Dysguisa and dry eyes but neither seem to show up in routine tests anymore, since dropping these medications. Which leaves me thinking that the bad taste, changes in bowel habits/ digestion, itching (scalp and back) and Sicca must all be autonomic rather than the drying up of mucous membranes as you describe for yourself?

What I'm still very unclear about is that PoTS/ Dysautonomia can be secondary to Sjogren's amongst other connective tissue diseases. So how can we know which type of specialism these come under? Is it possible to have a type of Sjogrens that mainly presents neuropathicslly/ neurologically?
