Advacaat, but it had to be Warnicks, and My parents used to give me an eggcup full after each dose of horrible tasting medicine!
As I got older, it became freshly made Egg nogg, two whisked up raw eggs, sweetened with honey, and topped up with full cream milk, and finished with a splash of Sherry! It tasted quite nice, as long as you remembered to pass it through a sieve first to remove any lumpy bits left behind from the raw egg!
