As far as energy drinks go I prefer Monster Khoas and Rumba, but they're more like spiked juice then traditional energy drinks. I don't like Red Bull energy drinks, but enjoy their simply COLA that I posted earlier. It's not the common phosphoric acid cola though. It's more like the original Coke w/ very very little cocaine. If they made a version sweetened with stevia instead of sugar I could probably drink it every day. BTW, it's the sugar that causes most of the energy drink crash. Most of all I drink pure green tea w/out any sweetener or flavorings.
