I have heard of a few cases where people have died after drinking a lot of Red Bull.
Somehow I can't imagine someone's obituary in the paper stating 'Cause of death = Red Bull.' lol
I drink a lot of soda pops, some of them have about 6 teaspoons of sugar in them. I buy 2 packs of 6 everytime I go to the supermarket, and take about 4 to work with me at a time. It's the sugar I like them for. The glucose provides me with energy I can use at work.
Only drink redbull if I am feeling extra run down physically, or, if i'm mixing with vodka.
