I have found that organic powdered psyllium definitely helps avoid the liquid stool, but I have had to introduce it gradually. I have 2 t before breakfast and 1 t before other meals, in water. I started with 1 t. before each meal. I also have found that I don't excrete much at night if I have a lot of salt at my evening meal, as I retain the water instead of peeing/pooping it out. I have noticed that my guts are less irritable in general when food moves through more slowly. Psyllium in the above form seems pretty clean, but I always wonder if keeping stuff in my gut longer can offer bad flora or bacteria a longer time to grow? I make sure to eat something with probiotics in it with each meal to help the good flora.
