Can you imagine all the happy people strolling the streets with a smooth 7up in their hands?
The product was originally named “Bib Label Lithiated Lemon Lime Soda” (which I think is much better than ‘seven up‘) and had Lithium citrate in the formula, a mood stabilizing drug.
It was lunched a couple of weeks before the Wall street crash of 1929. No, It doesnt have to do with people jumping off buildings. The formula was changed after 1950 to remove the substance or any other patent medicine product which were popular at the late 19th and early 20th centuries.
