I haven't been able to find the Steven Seagal energy drink anywhere and I'm not entirely willing to drop $30+ per case from Amazon without actually trying it first.
Too many energy drinks end up blurring together in the flavor department. Bawls is actually among the most pleasant in terms of flavor. Then again, it's just a Guarana drink and not a blend like most energy drinks. I'd second the endorsement of Lost energy drink above, if for no other reason than the can design.
Back in like '95 or '96, I used to be able to find this one called Go-Go in a couple of different terrible flavors. 'Flavors' is actually kind of inaccurate. They were basically different colors that more resembled sensations than flavor. My favorite one to describe was the red/pink one that really felt more like that instant after getting hit in the face where you're kinda like 'is that blood I taste? I'm not sure.' There was a purple one that resembled the feeling you get in the back of your throat when you have a sore throat/strep infection. Good times.
