You should chuck your pepto-bismol aside. If you have diarrhoea, immodium will do the trick. <br> As for the bugs being washed out with the poo, the aim of antidiarrhoeal treatment is symptomatic relief and prevention of complications like dehydration. Your body will take care of the toxins, and it will 'wash out' eventually. Your body is a well maintained and self correcting organism.<br> Of course, if your diarrhorea persists or is extremely watery (rice-water stools) or bloody, please seek medical attention to rule out cholera / salmonella for which a course of antibiotics will do the trick.<br><br>
