Does anyone else find it annoying when people eat really loudly?

I find it SOOO annoying when people munch really loudly. It's really affecting my daily life as I can't eat with my family - it pisses me off that much! I need a cure badly, does anyone else suffer with this? If so how did you stop! I've tried setting my mind elsewhere, but all I can hear is them munching away... Grrr!
