ddrobb, You might really be on to something with the seasonal change. I have a book that talks about that, it's the Brain/Gut, Body/Mind connection, I don't have the title quite right but it's fairly new. The book didn't go into super depth about it but recognized that seasonal changes can cause IBS flare ups. I hope you feel better soon. I alternate between C & D so I have an idea of how you feel. More water can't hurt but you might want to try a mild laxative like Phillips but I'm probably just stating the obvious. Good luck, Jackie
