Further, more than two thirds of these respondents said they would find cutting down on alcohol consumption more hard than making other lifestyle changes.
Launched in March 2016, One You from Public Health England is the first nationwide programme to support adults in making simple changes that can have a huge influence on their health, could help prevent diseases such as type 2 diabetes, cancer and heart disease and reduce risk of suffering a stroke or living with dementia, disability and frailty in later life.
Public Health England says introducing regular days off - preferably two consecutively - "will improve sleep while reducing the risk of heart disease, liver problems, cancers and high blood pressure", the paper adds.
Health chiefs in the United Kingdom are launching a "drink-free days" campaign to target regular drinkers amid fears health risks are "creeping" up on them.
Middle-aged people should have two consecutive alcohol-free days if they can, to reduce health risks.
Drink Free Days, launched by Public Health England and Drinkaware, is calling on people to reduce their alcohol consumption to lower the risk of developing serious health conditions, including seven types of cancer, high blood pressure and heart disease.
The tactic of having more so-called "drink free days" has been shown by evidence from behavioural science to be easier to achieve than reducing the number of drinks, particularly for those poll respondents who felt they would struggle to make changes to their drinking habits.
Pre-campaign research also found that the concept resonated strongly with people and was seen as clear to follow, positive and achievable.
Duncan Selbie, chief executive at Public Health England, said: "Many of us enjoy a drink - but it's all too easy to let our drinking creep up on us". It's also an easy way to pile on the pounds.
Professor Gilmore, the agency's chief external alcohol adviser, said that agency bosses were being duped into a partnership that would hamper efforts to reduce the amount Britain drank.
The campaign is being backed by former Liverpool and England footballer John Barnes.
This included a subset of 1,847 adults who drank over 14 units in the last week.
The Drink Free Days campaign will include an app to track how many days they have drunk alcohol and how they compare to the rest of the population.
The YouGov poll - by PHE and Drinkaware - surveyed almost 9,000 adults aged 18 to 85 during May and June this year.
