I have had IBS "D" for over 12 years now. I have had some constipation on and off but nothing serious. About 6 weeks ago I had the worse case of "D" in 12 years. After that I am now constipated all the time. It seems like my insides have just dried up. I have had "D" 2 times since that but it seems it is almost dry too. Does that make sense? It's like there is no liquid in my intestines for the "D" either. Has anyone ever had this problem before?
