Talking Rain was a popular caffeine-free soda there.

Bad idea.

Once, when I was less than a year out of school, I was in a design meeting with two of the most senior engineers on the project. They were WIRED, difficult to reason with, and sent me on an obviously wrong direction. I thought they drank 4-5 cups of coffee.

A few hours later I realized that the nonsense email that I got 10 minutes before the meeting, from the department head, titled "Lines in the conference room" meant that they probably snorted cocaine right before the meeting.

About a week later I had to redo all of my work using the exact design I pushed for. 2-3 weeks later I was relieved when I was laid off.

If you want to legally and safely know what cocaine feels like, take 600mg of caffeine pills (3 No-Doze) as soon as you wake up in the morning, on an empty stomach. Don't do it before you need to do something important, or if you're doing something where you could loose your temper. Also, don't do it if you have heart problems.
