I do not really like those mouthwashes that are anything other than peppermint however…in a case where I do not have mouthwash in the house I will use lemon juice. That is right - just take some lemon juice and swish it around for a bit. It is kinda gross but not more discusting than walking around all day with that foul smelling breath. And the people that you talk to will thank you for doing this also!
