Asking for a friend:
A friend of mine, prior to every bowel movement fills a rubber syringe, the kind that looks like a blue rubber ball with a nozzle, with warm water and uses it as a an enema. She says that otherwise, it takes her hours to use the restroom for a bm. I asked her today "are you sure that's safe?" and she wasn't sure and asked me to find out. I've googled it but it keeps bringing up ads for chemical enemas and warning about those, witch obviously not the case here.
