Cofain 699 is totally different in taste and effect of the other "energy drinks". Yes, Cofain 699 is even the only one I would really call it energy drink, because the others I see no awake-making effect. Since you will most pushed by the sugar rush.
Cofain 699, however, has NEN unique (and also getting used to) taste. The first time I have even shaken me because Cofain 699 tastes like cold espresso carbonated. That sounds disgusting, it is. At least initially. But after a short time you realize then that he really brings Energy. If you drink it on an empty stomach, but he produced possibly. Still a side effect in laxative manner. But who is disappointed by other Energys and verspĆ¼hrt no more thrust, which I can only recommend Cofain 699. And the taste you get used to over time, and then he also tastes.
However, you should really drink a maximum of a can per day. In extreme cases, even two. But I think is more then just a health hazard. :)
However, the price of more than 3 per can is too expensive here. In "Sky" shops (not the TV stuff) he usually cost 1.59 + 0.25 deposit. Every now and then there's him then they're 30 cents cheaper offer. In what shops there are him, I do not know.
