Try Hydrochloric acid it is like the stomach acid to help digest food also take natural digestive enzymes, cayenne pepper too to help kill bad bacteria that cause these smells, but you have to take these things with every thing you eat. You may have lack of acids in your body like so many of us, that cause over growth of bad bacteria, or try apple cider vinegar and cayenne pepper with every thing you eat. Good luck and God bless.
