May be you need to put him into a rehabilitation center for alcohol deaddiction or may be get him treated by a psychiatrist who is attached with a psychiatric nursing home or a hospital having provisions for admissions. His condition needs to be medically supervised and monitored by trained practitioners/ clinicians to tackle withdrawal symptoms as well which family members might not be able to tackle solely (since you mentioned violent behavior as well). Hence, only counseling might not help , which ofcourse is an integral part of the entire programme. If you are in Chennai you can contact Psychiatric Dept, CMC Vellore.
Next Steps
Pharmacotherapy, Psychotherapy, Alcohol deaddiction program. Might require admission.
