I want to add that you should look out for alcohol incompatibilities with medications you are using. Metformin, for example. Small amounts of alcohol are not usually a problem. However, the complication, lactic acidosis, is more likely for someone who has chronic kidney problems, etc. and could be a reason for the doctor to recommend abstinence.
Check with your doctor who knows your history.
