i still have dodgy days once in a while, and i'll have spells of a few days with uncomfortable but not alarming gas or a little C. but i still think of myself as stable (i'm an A but all of my attacks were D) because, as rachel said, i feel okay. when my ibs is under control - i know that i can eat safely - that's stability for me. it doesn't mean that i won't get an attack if i eat french fries, or that i don't feel a little off once in a while, but the off days are every few weeks or months, rather than being counted in days. i also think an aspect of stability is that you've gone through the process of safely integrating IF foods and protein - going weeks without an attack, but living on sweetpotatoes and rice, isn't really stability to me.
