Every time your mind wanders to a craving, as soon as you realize it, say Refocus: and immediately substitute with a thought about one advantage not drinking brings you. Even if you have to do this 1,000 times a day at first, do it. Retrain your brain NOT to ruminate on cravings. It is a broken record. Change stations the minute you notice it. This also is training you to observe your thougbts rather then identify with them. Your cravings are NOT you!
