Mr. Silver - I too am not a professional but among the baptism by fire crowd.

You already know the bottom line - you can't make them stop drinking. Period. By restricting their amounts, diluting their alcohol, etc. all you're doing is enabling them. This, in my opinion, is doing more harm to you personally and your relationship with your parents.

What I would suggest is to bring this information to the attention of their doctors and seek professional guidance. If someone at the facility is providing alcohol that needs to be addressed for a multitude of reasons.

This may sound a bit cold, but it's not your responsibility to make them stop drinking, even as much as you may want too. That is a part of the sickness of alcoholism. If you haven't already done so, you may want to join Al-Anon. I credit them with saving my life and sanity as I got very caught up with feeling responsible for the fact that my ex was drinking and destroying our lives. It was eye opening the extent that I was responsibile for, but it in no way was for how and why he was drinking.

You are an intelligent and compassionate man. Take care of yourself and Silver family first and foremost. Let the professionals guide you with the decisions to be made reguarding your parents. Alcoholism is a family disease and it's effects are far reaching.

Best of luck to you!
