I've stopped drinking 1y and half ago and will never go back on it, I save money, health and time.
I may not be going out as much as before, but I've started kickboxing instead and it turns out that people who are serious about sports do not drink, so going to the club is my new, non-alcoholic, socializing.
This comment clearly expands the point I made in my original comment above. When I say nobody regrets giving up alcohol, I don't just mean people addicted.
Even casual drinkers I know are so happy after giving up. They are more happy, sleep better, feel better etc.
The "socializing" people used to do with drinking, they are now replacing it by joining gyms, running marathons/ironmans and learning martial arts.
