I’ve just been prescribed a cough syrup called Grilinctus. The name sounds less like a cough syrup and more like a large, furry animal that’ll crawl out of the Forbidden Forest at night and will be fed and befriended by Hagrid.
The label on the bottle promises that the concoction is non-narcotic. This factoid hasn’t stopped it from inducing spells of sweet slumber that all cough syrups are so good at bringing you down with.
