What an interesting topic Kate
I get worried too when people disappear and we don't hear from them.
I first came on here a couple of years ago under a different name. Each time after serious binges and with a vague notion that I should stop drinking. Both times I lasted about 5 days. The hangover faded and I returned to my 'normal life' of alcohol prescription and denial, feeling a bit ridiculous that I'd bothered people on a forum. I mean I wasn't one of them right?!
This time I knew it was for real. I don't know why, but I did. My earlier experience of SR and its members brought me back with a New name and new attitude. Almost 5 months later and I'm still here. I hope others that go away return like I did and sooner than I did too.
