^ I've never seen a drink desperately try to pander to young people as much as Relentless. Except for Becks. Becks is a shameless tramp.
We all get run down from time to time and need a little boost to continue on with our daily stresses. But no matter how dire your exhaustion may be, never drink Relentless. Never. Once you get past the foul taste of raw jelly and suffering, it's only a short matter of time before you feel the poison's deadly effects. Make no bones about it, you have just drunk pure thunder. Your insides will be shaking with uncomfortable amounts of energy, with the over-jittery sensations slowly rearranging your internal organs and making sure there is no blood left in your caffeine stream. This is unbridled catastrophe in a can - people simply aren't built to consume a pint of sugar mixed with crack (I can only assume one of the ingredients is crack).
Also, the less said about the effects on your bowels, the better. Let's just say you won't enjoy your next trip to the loo. Or the one after. Possibly the one after that too.
