Your bad breath is probably systemic from your foods. You failed to mention personal hygeine habits. Do you brush? Floss? Brushing morning and night (for four minutes) in addition to flossing twice / day should be enough to curb your bad breath problem. However if the root cause is enzmatic in nature then the colloidal mists will help. Swishing H2O2 (Hydrogen-Peroxid) is also recommended from above.
