I have stumbled onto something that will put any legal energy drink to absolute shame. This stuff is called Boo Koo energy. It's 24oz. of complete caffein overdose. I had a can before I went to work. And an hour into it, I couldn't stop shaking. After it wore off, and I got out of work, I read the label on the can, and according to it you're only suppose to drink 2 servings in one sitting, and there are 3 servings in the can. It also has the "Children, pregnant women, people with heart conditions, people sensitive to caffein" don't drink it thing. It tastes pretty good too.
