Just to add here that when I was a daily drinker, it actually was more fun to drink secretly! My AH didn't mind me drinking at all but I still liked to hide and steal extra alcohol. Insane, I know. It gave more of a buzz at the time and re-enforced my insane alcoholic thinking of how clever I was.
I have spoken to other recovering A's and they shared they were the same.
Part of our insane denial was to believe that we were cleverer than other 'ordinary' people.
I can remember thinking this way and thinking it was perfectly fine, it is only now some years into recovery I see how utterly nuts it is.
My AH likes to drink extra secretly now. I don't care how much he drinks and he knows this but he still likes to do some secret drinking for the extra kick!
It is all insane.
