Hmmm... that IS troubling.
Have you sought some advice for the EMOTIONAL stuff going on???
Often, intestinal issues are reflections of our emotional lives. For example, I get constipated, and often "hold on" to my sh*t...(excuse the colloquialism). I have a hard time of letting go of anger and upset. THat's me...on your side, it seems that you've got an emotional flow that you can't stop. MAybe it's about work and giving to the children too much of yourself? Maybe it's difficulty in setting boundaries?
So, what is "runny" for you? I've found that people who have been trained in colonics and colon cleansing are often very helpful in exploring these issues. If Allopathic medicine isn't working for you, are you interested in looking at the integral reasons for this health concern?
