This is not possible. Your husband is not telling the truth.

No doctor in this world will advise somebody to take alcohol. The doctors know well that alcohol in small quantities is good and in excess bad for our health.

Alcohol can make one an addict. There are hundreds of millions of addicts in our world. They not only destroy them but also their whole family.

The calories what we take from alcohol is only empty calories and alcohol is not necessary for our metabolism.

Even the good red wine in small quantity is also not recommended by the doctors. They know well that from one glass it can become 3 and after that one bottle or more.

Talk to your husband and explain him everything. After that he has to decide.
