    I need to have a revision 'all-nighter' tonight so I got a litre bottle of supermarket brand redbull and so far i've drank 500ml and I feel sleepy - why doesn't it do what it says on the label?

    It hasn't 'stimulated' my mind and it's certainly not 'high impact'. Apparently it has a high caffeine content (30mg/100ml) - is it the drink or me??

    I thought I'd be wide awake but I'm knackered .

    I usually drink 'plusssz active'. It has 60mg of caffeine in one dose. Though it's a Polish product.
