The RAC 124 drink

RAC 124 (energy drink)
It was a minor UK energy drink of the mid 2000's.

The Drink.
It was a stimulation drink that was designed by both the RAC and the makers of the drink Sprite (soft drink) to help get tired motorists home safely if they felt sleepy at the wheel. It was intended to give the driker a 15-30 minuet boost at most.

The taste.
It was a more lemony variant of Sprite, which proved very popular in the UK.

Controversy.
Many motorists took it as an apparent cure for fatigue, but of coarse it was not, and some drivers even crashed as a result of it. It was later withdrawn since the RAC felt it was sadly being abused by people who should have known better.
