How to be as healthy of an alcoholic as possible?

Title says it all. I’m aware this is a deeply unhealthy way of thinking and some of you are kind enough to want to offer a helping hand, but I’m honestly uninterested in any support at this time.

I’m 25 and many years of drinking have taken their toll on my physical health. Besides quitting, what are some of the best things I can do to combat the harm? Mainly to the liver but all advice appreciated.
