I do like to ride the Bull every now and then - problem is if you start early you can end up in a Bull hole by the end of the day and you can't climb out of it.
I've drunk Red Bull on and off since it came out in the UK what, 14 years or so ago? I love the flavour, if it was produced as a non-energy drink at Coca cola prices and just a standard fizzy drink I'd go through a lot more of it.
Tesco KX is alright considering it's a fraction of the cost.
