Not sure if you mean it seriously or not. Not even sure to what degree this is accurate, but definitely to some, because coffee is probably[0] most common form of self-medication on the planet, followed by cigarettes, and then alcohol and weed are two well-known anesthetics and sedatives.

It's somewhat common view that coffee is the one legal performance drug almost everyone uses to keep up with their job demands, but it's less recognized that it can - and likely is - used to cope with other people. Alcohol is definitely used for the latter.
