Actually, I agree with the author. While writing a book, I needed all the productive time I could have so I stopped drinking too. I only drank once a week, but I could definitely notice that my brain was much sharper without having had alcohol the day before. Say that you drink once a week, then not drinking provides 2 to 4 hours of extra focus hours per week (if not more) which is a lot. Also, being the first to be running around and doing things on the day after a big party feels like a superpower too
