I ate an organic whole foods diet for years but it wasn't until I went Gluten Free that my body inflamation went down. I went GF 18 months before I was finally diagnosed and it reduced my daily pain by 90%!
Turns out my son is gluten intolerant as well. Once he was GF he grew 4 inches in 2 months and still seems to be catching up. All his self control problems at school went out the window too, his teacher was amazed at the difference.

On a pharmaceutical note. My remaining pain level has pretty much been obliterated since I started Gabapentin. It's harder to tell when I'm reaching fatigue status but it's only been a week. So I've got some things to learn about my signs not being pain related.
