I need to know how do you get rid of fishy breath?

Fish Breath: Stop eating fish. Sorry, bad breath is a topic of interest to many. First cover your bases. Consult your dentist, most bad breath is bacterial in origin. Make sure you have a healthy mouth. Evaluate your diet for foods rich in sulfur compounds, give breath rx a try if listerine isn't your thing. There maybe medical and/or dental issues, have examinations and investigate.
