One thing that helped me was changing my relationship with alcohol. It went from something I wanted to something I despise.
Here’s a thread about it: Change your Relationship with Alcohol
In the early days, I also had to avoid the people, places and things I associated with drinking. By avoiding those triggers, it allowed me to focus on building my sober network, learning the tools to be and stay sober and finally change my relationship with alcohol. I did all that here, on this forum.
