Thanks for the response.

I'm actually trying to think out-of-the-box from a causal standpoint. I'm thinking of all the things that happened leading up to the onset of my SFN symptoms. The very first thing I can cite was when I took iron supplements for a low ferritin condition and tore up my digestive tract something fierce. I haven't been right since.

My full blown SFN symptoms didn't set in for about 10 weeks after that, but I think I was having milder symptoms from that point forward.

More to the point, I've been reading about betaine HCL and how it's helped some fibro people.
