i had similar experiences. i did those thing for so long that they became normal to me, like stopping at the store on the way home from work and drinking a couple on the ride.- in my mind that was normal, although it wasnt.
for some time after i got sober it felt abnormal to not stop at a store on the way home even if for a soda.
it took time to get from my head to my heart that what i used to do wasnt normal and it was ok to not stop at the store on the way home from work.
and be comfortable not stopping.
