Hello, I’m with Systane drops, but isn’t working

I do.plaquenil helps.also rest as is eye drops

I have RA, developed Fibromyalgia, Raynauds and Sjogrens. The Sjogrens is dreadful. I try to control it by adjusting my diet, sugarfree, very low caffeine and very low gluten, no dairy as I found these things aggravate the Sjogrens in particular. I also have eye drops with me at all times, use saline spray for nose and coconut oil for vaginal lubrication. I struggle with the fatigue. I also get nose and mouth sores.

How is Sjogrens diagnosed? I have most of the symptoms.

I have very dry eyes, the Optometrist said to mention it to my RA, for now I'm using Systane drops or gel.
