I love the one made by powerade, don't know what it was called though. I can't drink it really though. For some reason I have a strange reaction to it, when I orgasm I get a pounding headache that gets worse and worse leading up to the point, then I have one massive pain orgasm, and then it goes away. Basically, down south feels good, head feels like I'm about to die/explode. I can't remember if red bull did this, as I've only drank it a few times, but I think it might have as well. The pain follows the same cycle and pattern as the pleasure, it's strange.
