yerba mate is an herbal tea from south america which contains similar psychoactive compounds as coffee, tea, and cocoa, as it contains caffeine and other similar alkaloids. http://en.wikipedia.org/wiki/Yerba_mate#Infusion
i believe its some type of hollowed out gourd and a specialized straw or something. but its just how it's traditionally served, i'm pretty sure you can drink it however you want
never had it before, so i can't vouch for quality or anything, but they sell it here: http://www.guayaki.com/ also some organic/specialty groceries and coffee/tea shops and things like that will carry it, if you want to buy from a local store
do jagerbombs count? I just like tea, but an apple in the morning is supposed to give you more energy than a cup of coffee i guess. That is a healthy alternative if your looking for one. i cant really handle energy drinks my body gets to shaky for me
green dragon http://www.greendragonsoda.com/ , love "yerba mate" it's a nice tee if is dark green with loads of milk and 2/2 sugar , and water of course
If I want to feel like I did a small amount of meth then Redline, if i'm just looking for a little upper then Soda or venom energy drink (Black Mamba specificially)
