Ginseng in little bottles sold at truck stops for long haul truck drivers in the US, in Australia, are almost 80% alcohol.
A truck driver came to me and told me that he drank a little bottle of ginseng he bought at a truck stop, got back on the highway, was driving at 80 miles per hour and was shaking all the way. Literally shaking while driving at 80 miles per hour !
Coca Cola and caffeine drinks with sufficiently high doses of caffeine work as well. I used to drink Coke when I drove during late night from Reno to San Francisco (about 4 and a half hours).
