I had to change a lot of things. One of those was my social circle. I'd ended up in a group that drank as hard as i did or worse.
Some of them supported my not drinking but most drifted away.
I didn't isolate tho - I reconnected with old fried whom my drinkign had driven away and I made new ones.
The friends I lost I consider weren't true friends anyway - the only connection we had was drinking.
