For the past 6 years I have been drinking 1 liters of Euro Shopper energy drink every single day. I am addicted but I don't want to stop because it's cheap and I like it. I am not overweight at all, and I exercise regularly. Is it still dangerous?
If the source from wikipedia is correct, 1 liter of Euro Shopper contain about 320mg of caffeine, which is equivalent to 3-5 cups of coffee. I can't imagine that this will be dangerous. Some times energy drinks contain other stimulants, such as ginseng and guarana, which may potentiate the effect of coffeine or in the case of guarana, contain coffeine themself. Therefore it can be difficult to know exactly how much caffeine and how potent an energy drink is, but I still don't think it's particularly dangerous. A bigger concern is the amount of sugar in it, but I guess you are aware of that.
Possible side effects are insomnia, anxiety, irritability, diarrhea, increased blood pressure, heart palptations and very rarely heart arrhythmias.
