I stumbled on some Yerba Mate tea, which proportedly had all sorts of health benefits (better for you than green tea) and provides a HUGE jolt of energy without having the drawlbacks of "normal" caffeinated drinks. I tried tea bags of Mate Chocolatte, and greener green tea mate, and loose leaf of the standard, the mocha maca, and Vanilla Nut in a traditional Mate Gourd (see pic below) with traditional Bombilla metal filter straw, and it is really some outstanding stuff. Tastes great, provides one HELL of a kick in the pants, and is healthy. I am a convert!
