The more time I didn't drink, the easier it got for me, even though I slipped up several times. Learning to say no to the AV is the hardest part, but incredibly effective when practiced. I tried several quit methods but the strongest and most successful has been when I just say NO to the AV immediately. The second the thought occurs that a drink might be good, for whatever reason.. shut it down IMMEDIATELY.
Do not give your AV a seat at the table so to speak - the opportunity to have a "discussion" with you about why a drink would be good. I ALWAYS failed when that happened because it can use incredible rationalizations, and the longer we ponder it, the weaker we become.
Shut it down immediately. After a while, it goes away, because you have eliminated a "train of thinking" that gives it voice.
