My aunt has Sjogrens and Celiac, and her symptoms are also the same. She
uses Restasis, and mouthwash for the dry mouth. I also have to take vitamin D, when my level was found to be virtually 0! I take magnesium & calcium as well, even though those came back normal (I have always taken them, especially since I can't drink milk). Try the vitamin D, to see if that helps.
