Realizing that I'm replying to a very old message... A coffee enema would not seem like a good idea after a longish fast either. Do you really want to put coffee in your intestines at this point? They might be in whatever weakened repair state. Also, are you sure you want gall in your intestines, for the same reason? I'm suspicious about coffee enemas in any case, not in the least because I think provoking bile flow into your intestines without any food being there could be irritating, but after a fast it seems especially unwise.
