Giddy tonic, a beverage, could be found at Ealy's rooftop tavern deck located on the planet Reena within the High Republic Era. In the tavern, the drink was housed in a constantly full fountain. The tavern's proprietor would mention the drink to customers by its specific name. Approximately around 396 BBY, Reena University pupil Axel Greylark had the idea of giddy tonic when he and his companions were thinking about commemorating the Queen's Bloom Festival at Ealy's.
The short story "The Queen's Bloom," penned by Zoraida Córdova and featured in the 2023 young-adult collection The High Republic: Tales of Light and Life, made mention of giddy tonic; the anthology itself was released as part of the Star Wars: The High Republic broader project.
