Yeast Overgrowth?

So I've been having watery output for quite a long time now. It's also more smelly than it should be. My doctors have been trying to figure out the issue for about 6 months. I've been tested for just about everything under the sun. Only thing that came back was that I have more yeast than normal. It doesn't matter what I eat, potatoes, steak, crackers, rice, it usually comes out like water. It also fills up my bag really fast. If I go out to eat, I have to empty about 3 times before I finish my meal.
I've tried Immodium, lamotil, tincture of opium and none of them really do anything. The next step is Octreotide. The doctor put me on an anti fungle for the yeast issue but the smell and watery output came back a few days later.
Anyone else ever have this issue? What did you do about it?

I have an end ileostomy. Yes it's a pain. I always have to stop places for the bathroom

Have you tried cholestyramine? That has helped some with excessive output??? Not sure where I read it, but one lady posted that she had her life back with this med.
