Welcome to Healthcare magic.
Alcohol damages liver.
But if there is a damage to liver , the AST is raised more than the ALT and it is not so in your case.
So a damage to liver is less likely.
The ALT is also raised less that 2 times the upper limit of normal which is not significant.
You can have a ultrasound
scan of the abdomen done to rule out fatty liver
Since you have already stopped drinking alcohol, there is no need to worry as your blood tests do not indicate anything very serious.
