hello and welcome to healthcare magic forum.
Homoepathically speaking this diarrhea
is not due some bug but a predisposition. which will go away by just correcting your diet for sometime. Otherwise if you need a medicine which is mild yet powerful in stopping your trouble then I would advise you to tke sulphur 30 6 pills once at night before sleeping. for five days and you will get a good releif.
wishing you good health!
