  1. Listerine used to work for me, now I still am having issues. I think it is probably what I m eating as I eat ALOT of salad onions. Would this make sense?

  2. I have bad breath after I exercise every time. I am trying to lose weight and having bad breath after exercise is making me embarrassed. Is there anything I can do?
