Make it your First and only Day One, or better yet change the nomenclature , the AV already has possession of it.
I think IT has you convinced whatever you were doing /calling it before was something more of a break-taking as opposed to an enough is enough event. When you keep calling those days by that name , they can come to mean 'the last time I stopped' in stead of the day I Quit days. You/we start talking thinking about them as though they can do reoccur, it becomes its habit, nip that in the bud.
Freedom Day, or Liberation Day , or actual FU AV Day, something that makes it Yours and not ITs.
