Swinging (no not that kind, Janice)

hey all, quick rundown- F30, have had IBS into an IBS diagnosis for years now. I have always been IBD-D, but recently for the first time I started having some issues getting backed up. Saw my gastro, was prescribed miralax, am very careful with it. Apparently, even with how cautious I am, my intestines decided to give me the proverbial middle finger and the last 3 weeks have been pretty awful; I have been alternating between miralax and Imodium in the smallest possible doses and still can't get this to calm down. Has anyone worked out even a few tricks to help regulate yourself tract during a flare where your body is constantly swinging between IBD-D and IBD-C? The only thing I'm finding that helps even a little is like, a small lake's worth of chamomile tea every day.
