Thanks Nancy, not long after posting this, I tried a small amount in a salad and was terribly bloated that evening. Nothing else I ate should've caused it so I'm assuming it was the walnuts. I hadn't had any nuts in a very long time. On a low FODMAP plan, some people can tolerate a small amount, I guess I'm not one of them.

Also, now it's day 5 of FC'ing and I'm feeling great. Still far less bloat and no real stomach problems. I'm also taking the digestive enzymes, so the combo of the two seem to be helping so far.
