Well, there's always the time-honored combo of pure prune and cranberry juice to facilitate semi-uncontrolled urination/defecation. From experience, a really cheap beer or two aids in uncontrollable bodily waste removal, so combining the two would be powerful. Of course, the alcohol brings all the inherent dangers and the pure juices still give you some measure of control.
Really, apart from that, I can only think of the stuff that is made for causing such situations, which you didn't want.
