Other things than alcohol can cause elevated liver enzymes. Being overweight is one also having hepatitis C or A or B
Since you have elevated liver enzymes until you see a doctor I would hold off on any alcohol consumption.
I’ve never had my b12 tested are you taking any supplements containing B12 I would stop taking any additional b12 supplements if that is the case.
Why did your doctor order these tests? Are you experiencing any symptoms related to liver disease?
