I can't remember the name of the medication for the ulcers but I think mine started with Tr. Sorry I know that doesn't help. I don't have Sjogrens. As for your fog...ME TOO! I used to have to have me husband and daughter post notes around to remind me: eat, take medicine, shower, brush teeth and I could drive because I would forget how to get home. But all that is better now.
I hope you are better soon!
Have a wonderful week!
