I am drinking one bottle right now as I type this and I feel none of the effects you have posted. Been drinking this for the last 2 weeks and so far I have not felt any traces of caffeine at all. Hey i have just found a batch of Viva Toro drinks at the local Zeller's store. A sure rip off of Red Bull! Cant wait to try this out! http://www.bevnet.com/reviews/vivatoro/
