Why astronauts are banned from getting drunk in space

BBC:

Travelling thousands of miles above the Earth, into the great inky unknown, is hard work. It’s stressful and scary. So why shouldn’t astronauts treat themselves to an end-of-Earth-day cocktail to unwind?

Unfortunately for space explorers looking to wet their whistle, consuming alcoholic beverages is widely prohibited by the government agencies that send them to places like the International Space Station.

Aside from the obvious reasons (“We don’t allow car drivers or jet pilots to be drunk and in charge of their vehicles”), there are many others you may not have thought about.
