When you drink alcohol regularly, your liver cells die and scars appear in their place. The more you drink, the more scars, and it eventually turns into cirrhosis. When you stop, it allows your liver to start to recover. It’s a slow process that requires a diet of no alcohol and not a lot of fatty foods.

Note, however, depending on the damage, it may never get back to 100%, but anything is better than requiring a liver transplant.
