I'm usually IBS-D. I had really bad D on Sunday night and Monday morning. I took some Immodium AD to help me. I also didn't take my Citrucel on Sunday or Monday night since I was feeling bad. I starting taking one tablet a night again on Tuesday night. I still haven't had a BM since Monday morning. I feel like I need to go, but then can't. Has anyone else experienced this? What can I eat to help me? Thanks.
