Welcome Corella,
You're in the right place, as far as I'm concerned.
It would help if you listed diagnoses, symptoms, and medications. It's in the signature line (you can see mine).
Are you taking anything for saliva production? Evoxac, Salagen (and pilocarpine which is the generic Salagen) are the drugs for saliva production. I couldn't survive without it.
Think about having a humidifier in your room.
I use a saline nasal spray, too, to help my nasal passages since they are so dry.
I use Simply Saline morning and night. Also RX Nasonex to reduce the post nasal drip which is so thick and blocks my nose at night. That makes me breathe through my mouth which turns it to sandpaper.
I used eye spray at night when I get up to pee. I have interstitial cystitis (IC) which is an inflammatory condition of my bladder (goes with Sjogren's very often).
Of course I drink a lot for the dryness and pee a lot because my bladder is irritable. Take about a vicious cycle!
I have NEVER ever tested positive for any autoimmune condition, Corella.
So my dryness is called Sicca, which is Latin for 'Dry'.
There aren't a lot of drugs for Sjogren's and the ones there (Plaquinel, which is a drug for malaria, and chemotherapy drugs like Methotrexate) don't stop the condition or cure it. But they do help for many. Also Prednisone, which will stop any sort of inflammation, and therefore the pain and misery that goes with it, but doesn't cure anything either. They are necessary and gratefully taken by many sufferers. But they have their own set of side effects, of course.
Hang in there, and look for all the tips and ideas you'll get here.
Many of us are sero-negative, or as I like to say 'sero-normal'.

Again, welcome.
Keep us posted.
Hugs.
Elaine
