That depends on how long you have been drinking and how much. Damage usually results over a period of time. There are many diseases that can be the result of excessive alcohol use including cirrhosis and hepatitis.
A measure of liver disease is from checking liver function test. Oe of the tests is for GGT, is a sensitive laboratory test for heavy drinking and can return to normal days to weeks after stopping the alcohol. ASt and ALT are also liver function tests that can check for any liver damage or disease. I would give yourself at least a few weeks.
