Energy Drinks Taboo: Red Bulls Kill?

Rumor getting from my email has it that Red Bull can cause numerous neuronal diseases and multiple organs dysfunctions if mixed with alcohol.

I googled and found out this has been spread in internet for a few years with various versions, talking about fatality caused by mixture of energy drink with alcohol, large quantity use, scary effects never learnt before regarding their major component, Taurine, Caffeine, even more convincing and scientific Glucoronolactone.

Wikipedia helps in clarifying these chemicals but the article below is more integrated one:
Taurine + Energy Drinks: Meant to Be or Doomed

So the conclusion for energy drinks:
Never drink excessively, particularly more than 3-4 cans at one time.
