I used this method, along with keeping a log of drinks consumed, to eventually quite drinking over the course of a year. I went from having anywhere from 3-8 drinks a night, every night, to eventually stopping completely. In turn I've been sober 6 years now.
I found keeping the drink log useful both for charting my progress, and also just forcing me to be honest with myself about what I did and did not drink. It's too easy to skew ones memory in favor of having less of a problem if you feel like it.
I would highly encourage you look into The Sinclair Method. It's based on the work of Dr Roy Eskapa and a book called The Cure for Alcoholism.
I struggled with alcohol for all of my adult life. Trying every thing possible to moderate or stop - AA, hypnosis, strange chinese herbs, counselling until I was blue in the face but The Sinclair Method worked like magic. For years now I have been entirely indifferent to alchohol and and my life is so much better for it.
There's a subreddit with lots of info and support if you're interested. https://www.reddit.com/r/Alcoholism_Medication/
All the best.
