Hi ichigo! So glad I found your post, as my main problem is also bad breath.. I have read countless articles on the topic, went on many, many websites, forums and was able to narrow down the cause of my problem to post-nasal drip, which causes bad breath and can be caused by candida overgrowth. What has really helped me is to mix 1tsp of salt + a pinch of baking soda in a cup of warm water and to use it to “rinse” my nose with it, to get rid of mucus located at the back of my throat. (Post-nasal drip happens when your mucus production has gone out of whack). It works. When I first tried it, my breath was fresh for the very first time in years, but it is only temporary!
