You need to READ THE LABEL before drinking Anything anyway!! I used to drink RED BULL all the time when I lived in Thailand & when I served in Viet Nam. You DON'T know what you are talking about, It isn't the Caffene that drives you from Red Bull... It's INOSITOL,B6,B12..... It isn't dangerous with the exception that if you are old, you have high blood pressure, you have heart trouble etc. If You Have All these things OR Any of these things, YOU need to consult your doctor before taking vitamins or ingesting ANYTHING into your system. (Even Oatmeal Probably) The burning rush you felt on your skin was NIACIN..also in Red Bull. That Carbonated Crap that is sold for Red Bull here in the US has had it's vitamin content removed, Caffene added, and then a heavy carbonation. Only a Moron could think that Crap is better for you. Asian people have been drinking the Red Bull Vitamin/Energy drink for years with No Problems. Just curious.... wonder how many carcinogens got added to the US version during it's process of carbonation & chemical change???
