only with mixed drinks. the bars around here have the 'raging bull' - a mix of red bull and vodka, while a 'jager bomb' is a shot of jagermeister dropped in the drink (tastes like red pop).
red bull isn't really healthy, and it's way overpriced. the mixed drinks i mentioned cost more than the average at the bar, so usually i make sure someone else is buying.
if you want to stay awake you're better off buying caffeine pills and soda.
