Nothing inherently wrong with vigilance, if that's how you want to look at it. I prefer to refer to it as maintaining my motivation. To each their own.
I maintain my motivation by building a satisfying sober life. When I am occupied with stimulating activities I rarely even think about alcohol. It took several months to get out of the mindset of the drinking habit and into the mindset of my new alternatives, but it can be done.
Best of Luck on Your Journey!
