My personal experience certainly agrees with this. I definitely shouldn’t smoke on a work night, and it’s not a good idea on Sunday either. The more hours until I need to perform cognitively, the better. I abstained for months before the last time I did job interviews.

I'm over 40 and have worked crap jobs most of my life.

It isn't like it makes me stupid. I simply think differently and that isn't all bad. Cleaning house and other mundane chores are less bothersome, and my life is full of this mundane crap. It also isn't like being drunk and I can still participate in society (I personally don't drive and just use public transport, sober or not)
