It sounds awful, but I've had it numerous times. The closest taste I can think to compare it to is Smarties candy. Mix about half and half Jagermeister and sugar-free Red Bull together (normal is NOT the same flavor). It's VERY tasty, though I can't recommend either half on its own.

Hangover treatment: Gatorade and a /little/ vodka. And then as much water as you can drink. Then go back to bed for a couple of hours.
