Hello! Need some help. I have IBS-M. Mostly I have constipation but the past week it has been diarrhea only. Painful diarrhea after everything I eat or drink. Being its Easter season and I am the director of a church choir, I am very busy right now. Afraid to eat because I know I’ll end up in the bathroom when I should be directing. Have limited my diet to dry toast and unsweetened applesauce mostly with some white rice and chicken. How long can an ibs attack last?
