Hey...interesting question...the definition of addiction though I feel is when it overrides everything else in your life...I doubt that counting days will ever do that. While in early sobriety I clung onto the amount of days I was sober I tend to just count the months now. Sometimes though I go into sober time and have a look at how many days I am...I remember when I was over 400 (am nearly 600 now I think) I was totally blown away. Days felt like years when I was using and minutes felt like days. Sometimes its just a bit of a boost to realise just how long it is you've been sober.
Wishing you all the best....in the days....or maybe years to come!!
