Yes, I do use the app and I love it! I'm like you, though, and still get unpredictable episodes. I never went through the complete elimination phase, as I really thought I had a pretty good handle on what my triggers were. Unfortunately, I'm still plagued by unknown surprises. I find that if I eat at home and am in total control of what goes into my food, I (not surprisingly) do quite well. It's when I try to eat out or at someone else's house that I get into trouble--there always seems to be some hidden FODMAPS.
Did you have any of this trouble before your surgery? I was plagued by UC problems, but not like this. I'm trying to understand how having a colectomy essentially induced this FODMAP intolerance. I guess the entire gastro microbiome was changed? I'm also wondering if I would just be happier going to a permanent ileostomy or if I would still be plagued by problems. I really love to eat and I love good food, so this has been very difficult for me. But at least I'm eating...
