AA working or not?

I have a question concerning drinking. Situation: mid sixtiy y/o adult. Been a drinker (mainly wine) for 40+ yeras. Now, less volume brings on more antisocial behavior. i.e. 20 years ago 2 or 3 glasses, not really a problem for me, never a problem for the drinker (that he/she recognizines). Now only 3 or so glasses of wine makes for some very antisocial behavior and actions. They have attended a couple AA meetings after a visit with a physician and a counseler, which is a requirement. Some days there is no drinking (maybe 3 or 4 times a month) other times (last night for instance) 3 glasses of white wine made a very ugly situation around the house.

QUESTION: Is it normal, while being a semi regular AA attendant to continue drinking?

Drinking here: never less then 2 glasses at a session, some times 8 glasses per evening. The drinking usually starts mid afternoon.

I was told by someone that tapering off was the norm and cold turkey was rare. Someone told me once that a stork brought babies to the hospital too!
