Pud, you mentioned that you have SIBO. We suspect that I too have this but haven't confirmed with the breath test - that's a long story I won't bother you with. But, I'm wondering if you had any success at all with antibiotics? I've read that people often have good success while they're on it, but it doesn't help all people long term.
I'm also curious to know if you've tried any probiotics. You may have seen my posts about the Udo's Choice I've been taking and getting fantastic results. I seriously doubt that it's going to make all of my symptoms disappear permanently, but so far with the diet and probiotic, I finally have quality back in my life.
