Update: a few days after the post above, I had a terrible autoimmune attack, heard a podcast on that very subject, and read the book Arthritis: the best thing that ever happened to me.

Then I embarked on a three day fast, which tempered my flare, and began a ketosis program, with a daily average of 10 carbs.

One month later, I'm feeling so much better, there's signs of continuing healing, and I'm only taking 1.5k a day of the niacin.
