I suffer from IBS-C and have been on Zelnorm for over 1 year. It seems to have stopped working. I'm currently on the Mayo suggested 3 TSP Konsyl 4TBL MOM daily. Further I've kicked it off with a mostly liquid diet. I have not taken the Zelnorm in a week, I feel I may have a tolerance built up some how. Thing is I need to get the Zelnorm or some other pill that works because I joined the military when I was feeling better and leave for BCT soon. When I got on Zelnorm I got 7 months of normal life, I coulda gone through then. Ive got till mid march to get this going again. Idea's?
