Red Bull Is addictive, however it does taste nice and I find it gives me that little bit more energy. If your trying it for the first time dont drink it near your bedtime(you will not sleep and it will keep you wide awake for hours) and do what it says on the bottle/can.
There is a reason why they say dont have in excess of 2 drinks of this a day and if your a caffine sensitive person be careful. Not recommended for pregnant or lactating women. And do not give to children.
