I lost a good may people I considered friends when I got sober.
From the vantage point of a decade on I can see a relationship built largely or even completely on a shared love of getting wasted was probably not that great to begin with.
A very few of my drinking buddies stuck by me and even decided by themselves not to drink around me. Those are the folks I consider real friends.
I gained a lot of new friends and reconnected with old ones my drinking had driven away.
I regret nothing
