While I don't have RA, I had osteoarthritis in my hands bad enough to wake me up in the middle of the night. But since going gluten-free (I was already low carb but would have bites of things here and there) that pain has lessened by 90%. When I added zero-balancing (a type of massage therapy) to the mix it retreated even further.

Some folks on the forum are on Dr. Teresa Wahl's Anti-Inflammatory Diet, which emphasizes vegetables, while I'm doing Dr. Jack Kruse's Epi-Paleo, which is also Anti-Inflammatory, and emphasizes seafood and strict "sleep hygiene." I am very pleased with my progress -- I have Cortisol Resistance which gave me terrible fatigue as a primary symptom. I would say at my low point I was running maybe 30-35% of normal. Now, I'd say I'm up to 80%!

Since you mentioned fatigue as an issue I'd be glad to share what I've learned.
