Having never been on a cruise ship have no knowledge of this fact.Never the less a nurse friend of mine, was working on a cruieliner as a nurse. She claimes because many people were over eating and drinking that she had several request from passengers that needed enema. It was also not un common to have a passenger complain of being constipated after over eating, so it was just common practice to give them an enema.
Any one else heard of this.
