I'm compelled to vote for Verve! because my stepson is in Vemma's social network marketing pyramid scheme. You should all sign up to be under him in the pyramid. PM for contact info.
Not a fan of energy drinks, Coffee will do just fine. Besides only heard of 2 of them, know doubt the rest of them aren't availble in many countries outside of the US.
At the very least Rockstar, Monster and Red bull should be available in your country i believe. When i was in Australia, i tried this drink called Naughty G. Quite similar to Red bull in taste. I don't know if they sell it in the UK. http://www.naughtygdrink.com/whynaughtyg/canflavours.jpg
Coffee is my energy drink, but on occasion I'll have one of those new energy drinks. I can't say I get any more energy out of them than say a can of Coke, they're just much more expensive.
I forgot about coffee. Sorry about that. You guys can vote for coffee, tea and other energy drinks not mentioned in the poll under Other Brand Energy Drinks.
Also missing Lucozade Relentless V Red Rooster Burn Mountain Dew And many more http://en.wikipedia.org/wiki/List_of_energy_drinks
I based the poll on the more popular canned energy drinks sold in the US, which is the largest market for canned energy drinks in the world.
Another vote for coffee here. No cappuccinos or frappuccinos or lattes or any of that fancy-schmancy stuff. Plain coffee, and I take it black. Like my women. (Just kidding. I like women of all colors, though I'm partial to blondes.) 93 degrees Celsius? That's damn near boiling. That's lawsuit temperature.
