Thanks for taking the opinion . Just dont tell him to stop the alcohol Immediately . It needs detail counselling as what causes him to drink daily first . How did he get addicted to it . Yes I understand he is not willing to speak . We need to get the confidence from him That we / family members wont judge him for drinking . Than he can can start sharing what is his feeling and what makes him to drink alcohol . Pls dont force or go in rush to stop alcohol as it may harm him more . If any help Psychiatrist would be the person to help in a better way .
