Bad Breath coming from mainly the throat/tongue fix?

Ok so in the mornings i have perfect breath until right before lunch i get this horrible rush of bad breath then when i eat lunch it goes away and about 20 minutes after lunch it comes back twice as bad as the first time. Any help?

Note: I brush my tongue, use mouthwash, its in school so no gum or candy. Can anyone maybe give me a homemade remedy?

Thanks

It generally comes from your teeth.

I don't know if they have them where you are, but Listerine make these little 'fresh breath' tabs. You just stick them on your tongue, they dissolve, and BAM, you gots fresh breath.

It sounds to me like it's related to when you're hungry. That's actually fairly common. Have you tried keeping snacks around, to see if that keeps it at bay?

Flossing. It could be crap stuck between teeth. Also drink plenty of water, i find that when i feel really thirsty my breath can wiff a little.
