Yeah they're called nodoz or vivarin. Live near a major highway, and you can pick up some interesting brands of trucker speed. Always a bit concerning to think of somebody driving tons of steel on the highway while hopped up on cheap stimulants.
It's probably not any worse than an assembly language programmer doped up on caffeine! :) ..but seriously, the a truck on the road can be a direct risk to others on the same road - not a good thought.
