Thanks so much for all of that info. I firmly believe that my fibromyagia, RA, and IBS are all related. When I feel bloated and nauseous, those are the days when my joints and muscles hurt the most and I feel the most fatigued. It seems like a huge task to try and find out the offending foods, but I really am going to put in more effort. Hugs and pixie dust to all. Edited to add: A few weeks ago I started to take probiotic capsules, in the hopes of improving my stomach/intestine issues. I thought they were working fairly well until the last couple of days.
