The harmful effects of Listerine

My friend Robert, who works in the wine business, told me last night that he doesn't use mouthwash with alcohol in it because the trace amounts of alcohol that get into your body from the use of mouthwash cause "stress to the liver." The dude is a wine salesman. He drinks wine.

I love the guy, but he is a complete hypocritical, obsessive-compulsive maniac.
