Is it possible to damage your liver drinking 3 times a week for 3 years. having about 5 drinks each night?

A different question: It is impossible not to damage one's liver by doing this, because the alcohol is toxic to liver cells. So, by putting toxic alcohol into the liver every other day, the liver is for sure damaged. The question is, if the alcohol were to stop, or to decrease to one drink 3 times a week, would the liver be able to recover without permanent damage. One's primary care doctor can help answer that.
