In summary: I changed from my regular probiotic, Actimel, to Yakult. A handful of days later I've got a gutspocalypse. Part of me thinks there's a turf war going on between the Casei Immunitas and the Shirota.
Now, I've reverted to the Chemical Cork, but in the meantime does anyone know of brand-changing drama, or did I really just have a bad butty the other night?
