I hear ya! I have a redundant colon and I suppose IBS-C. I keep gaining weight though yet I eat well, work out, tons of water. But I am lucky if I go once a week. Miralax/fiber/ that stuff does nothing for me. I have tried Linzess. Didn’t work. If anything made my problem worse. Was on vacation last week. Had the whole bottle of magnesium citrate. No movement til 3 days later.
I’m not sure what I can do and trying without long term side affects. Hence how I got to these lovely conversations. But the fitting in clothes and relationship issues I am with you 100%. Nice to not feel so alone since no one I know goes through any of it.
