Liver Cleansing would give you the greatest benefit initially.
Alcohol is toxic to the liver and causes fibrosis.
Fibrosis causes congestion in the hundreds of tiny liver ducts and in time can turn into cirrhosis, which is scarring of the liver. The liver can also develop steatosis (Fatty Liver) and liver/gall stones.
Stopping drinking will allow the liver to recover and a flushing programme will help to clear out the congestion and stones.
