Chai Tea, Black tea, Green tea, lavender tea.... provide much caffeine for to be sustaining my gaming craze. Better for ya too... Constant energy drinks is like gall stones and diabetes in a can....
So I guess to answer your question, yes, in a way, I do drink a lot of "energy" drinks.
If you want something really good, get Chai tea, put in some extra cinnamon, a little vanilla and a tiny bit of hazelnut. Really freaking good, but it goes so fast...
