To start with I did tell a lot of people a lot of details. After a while it got a bit repetitive. So now if I'm away for work and they ask if I'm coming for drinks, I'll go with them but just say I don't drink anymore. Usually you get a strange look and a few questions.
"What you've never drank?"
"Do you just not like the taste?" (I'd love a strongbow cider, but I know I'd be dead in a few months if I did)
"Oh really, how long have you not drank?"
I'll usually tell them the turning point on why I stopped and how bad I was and how much I could drain in a sitting. Normally results in amazed faces and "Yeah, you probably shouldn't drink."
But I'll happily sit in a pub all night I've even been to a few night clubs. And it is an enjoyable experience. Watching the demise of people's behaviour. My works do over in Belfast in December was one that was most amusing!!
