I haven't with Red Bull
But I've drunk 4 cans of Relentless in an afternoon before.

Your head starts spinning, you're so giddy you can't focus on anything, and your heart ends up beating so fast it hurts.

I can still focus . . .
my head hurts like a bastard though. Pulse still OK, no palpitations - I'm not sensitive to caffeine, but the sugar load probably isn't such a great thing for anyone.

Relentless is fucking awesome
to me it feels like coming up off a pill, and I'm pretty sure I gurn a bit when I've had some. It's a truly euphoric experience. Tastes better than red bull too, by a fucking country mile. £1 a can near work. I'm off for one now!

Red Bull just doesn't work for me, and it gives the vom/shits.
