If you are looking for explicit permission, I will state the obvious in case you’ve missed it:
You don’t need anyone around you to join you. You do what’s best for you. You don’t need anyone’s permission. You do what’s best for you.
You have done plenty of alcohol research. You have tried making drinking rules. You’ve tried moderation. You’ve tried drinking. You know the results.
What you haven’t tried is a longer period of sobriety research, to see if you like it, to see if you feel better (you will).
It’s OK to not drink. Nobody needs to consume alcohol. Drinking is not required. You feel better without the booze. You can give it up.
