I went for complete overkill and chowed down 30mg/capsule for a week, then melted them into oil & made brownies so that I could halve and quarter the dose. Did that for another couple of weeks. If anything, it seemed too effective at slowing peristalsis and the pain had largely gone away, so I stopped using the CBD but kept on with the probiotic pills (but taking them at a double dose because I figure it doubles the chance that they’ll make it past my stomach.) I’ll finish by taking a different probiotic pill with a different spectrum of bacteria et al. That plus my from-scratch diet should seed & support a replenished gut biota.
