I’m guessing you can stop at any time if you want to? I’ve known older healthcare professionals that have approved and even encouraged one drink a night, but our understanding of the effects of drinking has evolved. I doubt doctors keeping up with the science would encourage it at this point. It would be like having someone come in that’s overweight. It doesn’t mean you’re unhealthy now, but it may be a factor that needs to be kept in check and working on it could prevent issues in the future.
