FINALLY I found a thread that describes precisely my issues! I have been battling cramping/incontinence issues for the past two years. The birth of my third child resulted in a huge episiotomy which I believe is the cause of my incontinence. It doesn't happen only when I run, either. It got to the point that I couldn't even go out to dinner with my husband- I'd eat a couple of bites and dissappear into the bathroom at the restaurant, while he sat alone at the table. My self diagnosis is IBS complicated with the incontinence caused by the damaged episiotomy tissues. What a HORRIBLE affliction it's been...Whenever I go out I have to know ahead of time where the bathroom is and stay within distance of it. I read a few months ago in a forum about the Immodium helping some people with similar problems so I started taking one every morning (the chewable kind, not that it makes a difference). My situation DRAMATICALLY improved. From what I've read so far there's no ill side effects with this therapy. Now before a race, long run or dinner out I take two that day and it's done the trick. I realize this might not work for everyone, but it was a Godsend to me. I feel like I got my life back! To all of you who suffer with this, I'm right there with you and sympathize immensely.
