First of all: Stool softeners are not for "women". They are gender neutral products for those whose diets and lifestyle cause them to have difficulty with hard stools.... It can be very painful and be the cause of a number of other bowel related problems such as colitis and very painful and discomforting hemorrhoids.
If yer looking for something to stop the runs, I recommend Imodium extra strength.... or even Pepto-Bismol (the diarrhea specialist).
A word of caution: Diarrhea is your body's way of saying, "get this evil shit out'a here" and in many cases, one should allow nature to take it's course so that the foreign material can actually be flushed out'a yer gut. However, it is oft times inconvenient to take time for such things to run their course....
Thats why we have Imodium and Pepto..... This problem is only about 10,000 years old.
Here endeth the lesson....
