Be careful with that stuff. Alcohol will always do some damage to the liver. Some liver cells will die off from a drinking session, but each time it will be very few and it takes many years, decades even for one to have problems. However, with Kava it is a different situation. It may do nothing bad to the liver even in high doses. However, if you have certain genetics, the damage that could take decades to occur from alcohol could happen basically overnight requiring a trip to the ER and possibly even causing you to need a liver transplant. Kratom is similar but the damage occurs to the gastrointestinal tract rather than the liver.
