Alcoholism is a disease and needs to be treated by a psychiatrist.  Please convince your husband to see a psychiatrist or even a general physician.

Alcohol dependence is associated with significant physical, mental and social problems. Physically, there can be liver failure, jaundice, vomiting of blood, passing blood in stools, stomach ulcers, damage to nerves of the body, swelling of legs, fluid collection in abdomen, and many more. Mentally, there is irreversible brain damage, worsening of anxiety or depression, triggering of psychosis and mood disorders, dementia, etc. From a social point of view, there may be isolation from neighbors or family, increased abusive behavior to children or spouses, legal problems, accidents, etc. Anti craving medications are available which will help to reduce the craving. Consult a psychiatrist with experience in deaddiction.

What is disturbing you,  his habit of alcoholism or he disturbing you while you are not interested.!! Sit  and talk to him when you feel he is normal that you are not happy about this habit,  and it concerns you a lot,  because  it affects his health too.
