I tried Immodium once (the first time I had diarrhea in Thailand), and it didn't work. I vaguely remember others claiming the same. Anyway, I had a look at Wikipedia, which says that Immodium merely paralyzes the sphincter, but does not fight the cause of diarrhea.

When I have diarrhea that does not disappear after a few days, I go to see a doctor, or now rather go to pharmacy and get ciprofloxacin which helps (prescription only in Europe, OTC in Thailand - drug resistancy and so on, one day someone will die because he is infected with a resistant strain, just because I didn't want to sit it out - literally!).
