Hmm, I wouldn�t recommend Diarolyte � although it�s up to you of course � as it has the tendency to solidify the poop and thus clog up the diarrhoea and passages where in fact you need to flush it out.
So drink plenty of water to replenish lost fluids and flush out the nasty bits and pieces, no fruit or dairy stuff and just eat dry toast when hungry until it passes.
Although why you would accept the medical opinion of us lot is beyond my comprehension. There are people in the world far more qualified to give you an opinion and a recommended treatment. Not sure, but I think they are called doctors. Anyway, check out your Yellow Pages, you might find one there.
