The government advises that people should not regularly drink more than the lower risk guidelines of 3-4 units of alcohol for men (equivalent to a pint and a half of 4% beer) and 2-3 units of alcohol for women (equivalent to a 175 ml glass of wine). ‘Regularly’ means drinking every day or most days of the week.
