Will red bull help me stay energized and up-beat for a concert?

Personally, Red Bull doesn't do anything for me except give me horrible jitters in my legs and mouth when it's wearing off. Maybe if caffeine usually makes you hyper, it'll work. Just to be safe, you may want to bring another one or some sugar packets (Paul Blart image, anyone?) in case it wears off earlier than expected. Don't chug two at one time, though, because it could give you heart palpitations or something.
