I feel this. As someone who has seen some real shit... I feel like that kind of intimacy in a professional environment could actually be detrimental.

I don't want to see my boss wasted. Nor do I ever want to fall in love with the hot scrum master again.

Bravo.

Being a mature adult who is interested in reality isn't "Puritan".

Do people actually gets trashed and wasted with their team though? Usually I find that there is a "work" portion where people head to the bar after work and have a few beers and get buzzed and talk about work. And then people leave and people break off into groups and the "friends" portion of the night starts, when you might actually get drunk with your group of friends from work. But there is no illusion that there is any connection to work at that point.

Being up all night actually is akin to drinking for your body, or so I’ve read. I’ve definitely felt the same effects from sleep deprivation.

I experienced something similar, when I stopped drinking alcohol for health reasons and still noticing mental impairment when staying at parties until morning.

Unless you drink a ton most of the hangover effect comes from sleep loss and dehydration.
