I know!! I didn't eat yesterday, I ate brown rice cereal and had a major attack!! This morning, I ate plain chicken and rice and ......no attack, yet!!! Maybe it was the oatmeal that was triggering my attacks. I wish there was one fiber that would work for ALL OF US, so we wouldn't have to continue to experiment with different ones at different doses.....It's a pain!! But, when we finally find what works it's amazing how it aleviates most of our pain!!!!
