Daphne, what worked for me in the early days was to change my daily routines. I had to plan to be doing something specific at the times when I would have been drinking. I had to be out or with my husband, definitely. Change the places you shop, the way you drive home from work, the time you have dinner - all those things help to break the habit of craving alcohol.
And, know that there are no simple answers or tricks. As Neo said, Don't drink.
