Hi Chris
Not sure if I have said this already but think that ginger will help a lot in getting the liver to work better( which will translate as more BM).Ginger is the major camlative for the liver and yours has had to work harder as there is no gall bladder for digestive support.Use it any which way you can tolerate it.
Just chop it raw, boil it for the juice or just straight juice it and mix with a fruit juice. it might make you feel sick but that feeling should go in 5 minutes long as you sit upright for 20 minutes for gravity, suport liver function.
Dont think the amount of bentonite clay will make your bowels explode. 1 teaspoon is not that much in water. f#2 might slow the bowels down thas all that would happen.
Which part of UK are you in? Was thinking of doing f#1 order now for myself.
