Can't agree more. The gigantic overprescription of potent antibiotics for poor, or no, indication, is considered the most important reason for the rising problem of multi-resistance of bacteriae. Even if not caring for anyone else, as posted above, the killing of beneficial gut germs, will by itself cause functional diarrhea. It may, however, also, and even more important, increase the risk of growth of the evil bacteriae all of us have in the guts, but without the normal bacterial flora dominating the environment, will lack the normal control of growth.
