I work on projects late into the night, practically to sunrise occasionally. I have an addiction to productivity and sometimes I'd rather do that than sleep. To keep myself up I make cup after cup of earl grey tea, and maybe make myself a peanut butter and nutella sandwich or something. I use hot cocoa as a creamer because I tend to let tea sit a while carelessly, and if it oversteeps, the cocoa will ease off the strong flavor. I figure why not combine those flavors into one thing? It'll help keep me up at night.
