I had a bit of that once. I was sober for about 8 years. But I forgot something in the last year and a half of that period that I can now see made the relapse very much on the cards, so I've had to figure out what that was and not forget it again. Joining SR and the effect that has in my life in general makes me feel pretty good about being able to face a similar situation again should it recur.
Every day presents itself with an endless series of forks in the road. I think alcoholics are wise to take the road less often travelled, a pro sobriety choice, which can often mean pausing to take stock.
