Is your coffee breath so terrible that you're even knocking yourself out when you talk?

Step 1: Mix Hydrogen Peroxide and Water

Mix about 1-1.5t each of hydrogen peroxide and water (50/50 mix). Gargle but do not swallow. Spit out. I usually do this before I brush my teeth.

Repeat daily until you notice your bad breath is gone. Sometimes it takes a week or so, but it actually works. Your hygienist may suddenly think you're doing an amazing job brushing and flossing, too.
