My father 45+ years is a heavy alcohol drinker and smoker. We are observing an abnormal behavior since from last 2 years when he is drunk. He is becoming more anger and shouting at others. And when he drinks continuously for 3+ days in day and night his condition becoming different than other days he is behaving like man with bad split. And his blood pressure is abnormal in condition. How could he get out from his addiction. How could he stops drinking. Please suggest better treatment or medicine that he has to does not know that he is under medication. That means have to give him medicine unknowingly.
