So I have basically figured out that I have what is considered IBS-D. This past weekend I went on vacation and for the first time in many years, I was constipated. I know that IBS symptoms can go back and forth, but as soon as I got home, I went back to my "normal" loose BM. I was wondering if the D is caused by anxiety and stress, so when I relaxed, the opposite happened? I also drank less caffeine (and unfortunately more alcohol) on the trip, and thought maybe that had something to do with it. I ate more and had less stomach discomfort, interestingly enough.Any ideas? Do other people notice a change between D and C depending on stress level?Thanks, Jen
