Generally have at least one energy drink a day, usually Monster or Relentless =/
I don't drink the stuff.
Dont drink anything with caffeine and especially would not touch red bull, I refuse to put a single penny into vettels wages.
I used to hammer Monster, but I've reduced my caffeine and sugar intake a huge amount since starting to lose weight, feeling much better for it.
Only time I have any form of energy drink now is either Jagerbombs or vodka Red Bull.
Zero, it's disgusting.
