7up, n.Trivia

7-Up contained a mood stabilizing drug until 1950 (lithium citrate)

7-Up launched a variation called "dnL" (the 7up logo turned upside down) and was basically the opposite of 7 Up: instead of a caffeine-free clear soda in a green bottle, it was a caffeinated green soda in a clear bottle

7up was originally touted as a cure for hangovers.
