Just wanted to say how great it is to find people just like me! I suffered 6 years with diahhrea and then like a switch it went to C. I started taking Zelnorm this weekend and it has been amazing. My boyfriend almost died of amazement when I told him I went 2 days in a row! So for all you ladies that haven't given it a shot yet, I suggest you try it. It's been a sanity saver for me!
