i do not have any post nasal drip or any sinus issues. and i never had bad breath issues until the candida which i am only six month's into. this was never a prior issue, nor a life long battle for me. i am trying to treat the underlying cause which has be the candida itself - if i didn't have it, i wouldn't have the breath issues. but for now i would like at least try and somewhat cover it up without having to chew gum or mints because i really can't have that stuff. i can't pinpoint exactly which symptom is causing the breath. i guess i could try the enzymes as someone suggested and in the mean time try to kill bacteria in my mouth with the h202 and baking soda and a few other suggestions that were offered. thanks for the advice!
