Hi It is advised to add disulfuram to his food without telling the patient. Disulfiram blocks the breakdown (metabolism) of alcohol by the body, causing unpleasant symptoms such as nausea and flushing of the skin, accelerated heart rate, shortness of breath, nausea, vomiting, throbbing headache, visual disturbance, mental confusion, Ptient would suffer a lot every time he takes alcohol.Finally patient would feel aversion for alcohol. For strict veg diet there is no medicine patient should be counceelled by a counceller to take strict veg diet by explaining the need of taking that diet for liver betterment.
