Ghost, I've been through this too. I didn't stop drinking right away - still held out hope that I could somehow control it. The seed was planted though - I knew I was in trouble, and after the 2nd one I had to admit my drinking days must end. I couldn't be safe unless I stopped all together - I couldn't trust myself to be careful and not drive. Once that first drink hits our system - we never know where it'll lead us.
I'm very glad you're posting about this. We all understand and care - we're in this together.
