Just don't drink, even a little, and it should improve over time.
Everyone seems to be on a different clock
I was also a binger and could go weeks or months not drinking.
When I finally quit, it took about 11/2 years to fully heal
but I was improving a lot in 6 months.
I got a daily planner to write down things I might forget and to plan
so it didn't hurt my work performance but the fuzzy brain did occur
off and on for quite a bit of time.
Good nutrition, sleep, and hydration really helped.
So did a strong exercise program and beginning a yoga / meditation practice.
Self-care and sobriety should do the trick.
Take it as lesson learned and don't make the mistake of thinking you can
"moderate" in the future and you should be fine
