I've never had to take immodium (knock on wood). I'm lucky I guess. Usually if I get liquid stools I take some Liquid IV hydration, a couple rounds generally resets my hydration levels and water absorption. Before that I often had to take Lomotil or something to slow things down, it's almost as if getting a little dehydrated triggers a response where further water absorption stops. Completely weird and counterintuitive. But yeah... hydrating quickly usually restarts better absorption and control.
