It all started with a hangover

There was a prolific — truly epic — moonshiner from ’round Pilot Mountain way named Buck O’Hairen. Everyone bought their 100-proof rotgut from Buck. But Buck was no fool. When he realized that the revenuers would ultimately win, he decided to throw a giant bash — one so giant, in fact, that a fire started and burned for 30 days. When Buck finally woke up, he suffered from the worst hangover in history, and vowed then and there that he was finished with moonshine. From there on out, he would cook up moonshine’s antidote, a drink that made people feel good afterward, instead of lousy. He called it "Legendary Sunshine".

From there, Sunshine, once known as "Buck O'Hairen's Legendary Sunshine" was created with the memory of the original moonshiner Buck O'Hairen in mind.

Eventually, "Legendary Sunshine" turned into the "Sunshine" as we know it today. A vitamin and electrolyte filled energy drink for the rest of us.
