It can be hard for someone to tell exactly how much alcohol they normally drink.

Accustomed drinkers are less aware of feeling drunk, so it may be a good idea to keep a diary of alcohol consumed over a period of time and make a note every time you have a drink.

Present advice on safe drinking is:

  • no more than two units of alcohol per day for women
  • no more than three units per day for men
  • you should have at least two drink-free days a week.

A unit of alcohol is:

  • Half a pint (250ml) of average strength beer.
  • 125ml glass of wine 8 per cent ABV.
  • One standard pub measure of spirits (25ml).
  • 25ml of fortified wine, such as sherry or port.

When drinking at home, people are mostly more generous, so it’s a good idea to get into the habit of using a spirit measure.

Staying within the ‘safe’ limits does not mean that a person is capable of driving a motor vehicle. When driving, it’s best not to drink at all.
