Take the starch water, or boiled water as much as one cup of rice, mixed with a little brown sugar (brown sugar), drink while still warm. Hose half an hour later, drink water as much as 2 cups. Do things like this regularly every morning and evening. If you regularly do, undoubtedly bad breath odor will disappear. Good luck.
