For me, at six months, I kind of had the same thing happen. I think my thought process was that I was at the point of no return. Did I want to continue on my sober path? At this point, I am so committed to sobriety, but not too committed in that I still didn't have a year. I think I felt this way because it still required a lot of work to be sober and I was tired of thinking about NOT drinking everyday. I had proven I could go six months without a drink so maybe that was enough. I think this is where the term "fake it til you make it" comes into play. Just keep doing what you are doing, ignore your AV and before you know it, you will have a year under your belt. From there it keeps getting easier and easier.
