IME, many people who drink a little too much or a lot too much, want company, and they will notice the abstainers or moderates and call them out. Come join us, come join us…
But once people get used to your new drinking rules, it will settle, and the social pressure will be no big deal.
I have given up alcohol for Lent before and enjoyed the experiment. Last year, I switched from wine to beer and I’m much happier and I drink less. I found that a 12 oz beer (one serving) is way way more satisfying than 5 oz of wine (one serving) — five ounces of wine felt like nothing, y’know?, and I would often drink more than 5 oz.
