Why does alcohol help me focus?

So I work remotely 100% for various customers in a senior IT role (contractor).

For probably about three or four years now. I’ve found having a few drinks in the evening in front of the laptop. Helps me correctly articulate and word emails better, and also I can write code and complete complicated tasks with ease.

Could this be an ADHD thing? A few drinks slowing me down to be able to focus?

BTW. I drink one evening a week, either out on a Friday for a few hours then might sit in front of the laptop for a few hours. Or at home for a few hours.

For the IT conscious – I don’t make production changes with a drink in hand lol. Everything is change and release managed.
