Before you try this; speak to your Health Care Professional i.e. doctor.
Rather then 10 mg of lomotil try using small amounts of Psyllium husk powder.
It's not easy to mix, but try mixing it with water, just small amounts, a tea spoonful twice a day, then build up gradually each day with just a bit more if needed. But Remember you don't want to be 'blocked up'; it has the ability to do that if you are already blocked up.
At the same time rest the pouch. Get nutritional drinks prescribed; they will have everything your body needs. Drink plain soups like tomato, chicken etc. but without stuff like croutons etc.
Report back please.
