Gday,
That sounds like a real uphill battle, are you harmless when intoxicated or do you get yourself into trouble? Once upon a life I used to get into trouble from drinking a lot so I had to quit.
First up I forced myself to stay sober for 1 year by totally changing my lifestyle. I moved out of the place I was living in as it was full of bad memories, moved to a different town and studied so that I could not go back on old habits I knew I was going to die or be seriously troubled by the amount I was drinking, and problems arising from it.
Then. I used to spend all my money BEFORE I could spend a dollar on alcohol, and I would tie all my money up by pre-paying rent, phone credit and gift cards so it was impossible for me to get alcohol.
THEN...I worked on my social skills, friendships, traumas and hobbies. For me, drinking was escapism and habit, and I had hundreds of friends at the pub but no one outside of there.
Do you have a few things in your life that you value more than drinking? can you turn all your attention to those things? Set yourself some small, achievable goals say on one of your benders "Im only going to have (2/3 max quantity you usually have)." Make it so you cant get any alcohol no matter what. Make drinking unpleasant, and all other things will seem better by way of comparison.
And what do you like about yourself? What are you good at? What are you bad at? Throw your energy into these things, and internally remodel your self esteem so you identify as a person who doesn't prioritise alcohol.
All the best, you can do it! And if think you can't, try again.
