most mouthwash markets itself as something to use after brushing, which is a terrible idea as you're just rinsing away the fluoride and good stuff from the toothpaste. i actually mouthwash 10 minutes before i brush if i'm doing it as part of my routine.
also don't use mouthwash before bed. most are alcohol-based and will dry your mouth out. a dry mouth will contribute to tooth decay a lot more than mouthwash will protect against it. i generally just keep a small bottle of mouthwash in my desk drawer at work and rinse with it if i've just had a bunch of black coffee or office cake or whatever.
