In an otherwise healthy individual, liver enzymes return to normal within 7-10 days of alcohol abstinence. However, simple fatty liver takes 3-6 months to reverse with total abstinence in normal weight active people, but fibrosis and cirrhosis never goes away.
Use your good liver tests as an emotional boost and sobriety incentive, as opposed to a comprehensive clean bill of health....just my 2 cents and best of luck!
