It depends: Running a marathon can kill off liver cells from the blood being diverted. They'll grow back in a few days -- even faster than your hair. Even if you've damaged your liver with drink to the point of cirrhosis, abstinence will allow for a fair amount of healing in many cases in a few months. New treatments that remove chronic viruses have cleared cirrhosis totally. Your liver's incredibly durable.
