Rethinking the question, life never runs smoothly, trials and low spots are a certainty, so rather than running smoothly I thought about when did sobriety become reliable.
That was very early on looking back. It didn' take me very long to get into some tough scrapes, getting fired on my first day back, getting onto a crazy relationship and being thrown out of it etc big emotional ups and downs, steep learning curves, lotsa pain, yet it never occured to me to drink.
Yet it never occured to me to drink. That is quite different to saying I decided not to drink. It just never occured to me. I was commited to the steps, the drink problem had been removed, and sobriety had become reliable no matter what life threw at me.
That was only a few weeks in.
