My GP told me not to use Imodium because all that does is slow the digestive process down and doesn't 'cure' the problem. I always take Dioralite (not sure of the spelling so please excuse if I got it wrong).....it comes in sachets and you mix the powder with 7 ounces of water and take after every 'visit' to the loo!....it replaces all the salts and electrolites your body loses and it does help to stop the 'runs'.......so hope this info helps.......oh and they come in different flavours the ones I had were Lemon, but you can also get it in blackcurrant..........you can even give it to small children as well..(as we did last year
)...but it worked!...
