Back when soft drinks made a name for themselves....

Atlanta, Georgia: August 15, 1903: Coca-Cola is called Coca-Cola for a reason. For the past 18 years since it was created in 1885, this renowned soft drink has contained some 9 milligrams of cocaine per 7 ounce glass and has a fairly large dose of the caffeine rich kola bean in every one of those servings, too. Those ingredients provide a powerful pick-me-up for thirsty customers everywhere. Cocaine combined with caffeine laden kola beans! Hence, the name Coca-Cola.
And it was invented/marketed as a hangover cure. And it would have been very good at that!
