Having never been a drinker (well, tried a bit as a kid but quickly realized it wasn't my thing) it wasn't until the last couple of years that I started to understand why people drink. Being in the early stages of a new company and wanting/needing to work insane hours is all fine and good but after a while of not being able to easily detach it's easy to find yourself being overly anxious and distant. Like, clinically so.
That being said, some people can use alcohol recreationally and some are more or less destined to use it as a crutch. I'm certainly in the latter category.
