Try some activated charcoal capsules (sold at the pharmacy as charcocaps or charcotabs). These work as well as Immodium but also have the added benefit of binding the toxins so they leave your bowel more quickly. It also helps reducing any associated gas pain. Take 3-4 to start with and then another 2-3 every time you have another 'movement'. Trust me this is the very best thing you could do .
