Silver Ice first, which sounds like it might have metallic, sharp edges inside. Let us all hope and pray that it does not.
FLAVOR: It's pretty citrus-y. Kind of chemical-y. I find it to be a perfectly acceptable flavor.
EFFECTIVENESS: Halfway through, it is working quite well. I haven't crossed over into giddy territory yet, but I am doing some vice presidential blogging for y'all and ANYTHING COULD HAPPEN (given enough taurine in my system, anyway). I'm 3/4 of the way through, and my legs are pretty shaky and I just made an MSPaint illustration, so I think you could say this shit is working.
Overall it worked very well and tasted just okay. I probably wouldn't get it again, but it's not gross or anything. Just try it yourself, okay?
*Apparently they were released on the Fourth of July FOR AMERICA.
