Some people could be underestimating their alcohol consumption by as much as 40% new government research has found.
Taking a snapshot into the nation's drinking habits, the Change4life campaign took a look into people's booze habits.
Getting test subjects to keep an alcohol diary, they found people were underestimating how much they'd had to drink in a week by up to 40%.
The research also found that across the country 80% of those that drink too much acknowledge the health risks but think of themselves at most as moderate drinkers.
The new campaign suggests people should cut down their drinking by a third, for the good of their health.
If you want a little incentive, if you were to cut down your booze intake by a third, you would save on average £33.35 a week or over £1,730 a year.
People would also cut out an average of 236 calories a day, working out to 1,658 calories a week.
Chief Medical Officer Professor Dame Sally Davies explained, 'I understand that people enjoy having a glass of wine or beer to unwind at the end of a busy day - but these drinks stack up and can increase your risk of high blood pressure, cancer or liver disease.'
She added, 'The alcohol guidelines recommend that men should not regularly drink more than three to four units a day and women should not regularly drink more than two to three units a day.'
Tips for cutting down your drinking including having booze-free days, not drinking at home before going on a night out, swapping to low-alcohol drinks or swapping to smaller glasses.
