Drinkaware says some people have increased their consumption of alcohol during the Covid-19 restrictions because they are anxious and bored.
A new survey from the charity says equal amounts of people - one in four - are drinking more and drinking less since the measures came into place.
CEO of drinkaware, Sheena Horgan, says it's good news that many people have used the time to examine their drinking habits.
"There is certainly positivity when you see that a quarter of people are drinking less.
"Alongside that 33% have said they have made positive changes to their drinking habits during the lockdown.
"I think when we look at our website figures - in the month of April alone we had 90,000 visits.
"People are clearly concerned, and people are clearly willing, and there's an appetite for change."
