Government guidelines advise that men should drink no more than 3-4 units per day and women should drink no more than 2-3 units per day. It’s also better for you to have at least 2 days each week when they don’t drink at all.
This advice replaces the old ’21 units a week for men and 14 units a week for women’ to try to encourage people to drink in moderation and therefore reduce the risks attached to binge drinking.
