I didn't socialise for the first 2 months of sobriety, I just kept to myself .
These days, I only go out to social events that the main event is non drink related.
If it's just about the drinking, then I don't go.
Most of my friends were heavy drinkers, I don't see them now as they lost interest in me when I stopped, but that suits me fine. I have a whole new sober life now, which is so much better.
