Cirrhotic livers do not repair at all. Good reason to stop drinking now and not wait for the point-of-no-return, which is cirrhosis. If your skin is turning yellow, you are in the end stages of liver degeneration, but there is still hope of self-repair even then, if the whole liver has not become cirrhotic.
CIRRHOSIS is considered by most experts as a self-perpetuating irreversible process.
For those who like scientific jargon: "Regenerative nodules may form in the fibrous septa but they are not necessary for the histological diagnosis of cirrhosis: as nodules alone without fibrosis do not constitute cirrhosis. In this disease, the nodularity of the liver is mostly the result of fibrosis dissecting the parenchyma in small uniform acinar or subacinar nodules in micronodular types and in lobular and plurilobular large non-uniform nodules in macronodular forms. Regenerative nodules develop in the midst of scars but are a late phenomenon. They are important, however, for the advancement and neoplastic transformation of the cirrhosis."
