I stick with Red Bull when I buy energy drinks, but then I only ever drink the stuff once or twice a month. It's alright on long road-trips or long days of studying/simracing, but I really prefer coffee for staying awake and fresh, at least on the first half of the day.
I guess you can tell them that too.. but i think they'll just throw away your message unless you can provide them with some useful info on why you think it tastes like piss
btw, we had a fight about this in school at boring class. witch is more unhealthy, 0.3 can of energy drink or 1.5 litre of coce. my friend says he is on a break from energy drinks pecause he says they are so bad to teeth and he comes fatter from them(hes little fat, not that fat but little fat) and he thinks it is more healthyer to drink 1.5 litre of coce than a 0.3 can of battery. what u think is unhealthyer?
edit:i got confirmed that the ph-value goes a tiny bit lower in coke so coke does more damage to teeth, does energy drinks have any else dangerous stuff?
