If it's a blue potion, I feel refreshed right away.

I am sensitive to bad breath and have tried many different types, but I think there is a reason why popular products are so widely used. I like that even a small amount makes me feel refreshed. I heard that gargling too much isn't good, so I use it once in the morning and once before bed; however, the freshness feels like it's blowing away germs, so this is my go-to Listerine Original product.
