bloodywits's blog post - Just a friendly piece of advice...

Regardless of what the packaging says, do not use the Listerine Quick-Dissolve Whitening Strips "on-the-go" unless you can brush your teeth once you get where you're going.

Otherwise you will spend the first 30 minutes of your work day nervously licking white foamy goo off your teeth and hoping nobody notices.

...or so I've heard...lol
