Chewin in the Chung

Approaching 21 hour mark. Decided I was going to need some help if I want to get any work done this morning, so I grabbed the 2mg Nicorette that I have had since the last time I tried to quit. The box says it expired Oct '03. I didn't even know chewing gum could expire. And when was the last time I tried to quit that the Nicorette has expired?
