how do I get rid of bad breath?

bad breath
Dodo asked:

I brush my teeth regularly, floss, brush my tongue, dont smoke, chew gum often. and still. STILL i get bad breath.
i think I have a stomach problem or something because sometimes I can feel a little chunk of something stuck in my throat, when I cough it up it smells like poo. literally. what the hell is this? it bugs the crap out of me because sometimes it sits in my throat for days and i can’t cough it up or it goes back down.
what is this and how do i get rid of it? thanks
