Giving up alcohol for a month after the excesses of Christmas is a popular pledge for many.
And a Norwich-based charity which supports people with drug or alcohol problems is hoping 'Dry January' could create a funding boost thanks to mocktail recipes from a Hollywood star and celebrity chef.
Hunger Games star and former Costessey High School pupil Sam Claflin and Delia Smith have provided booze-free cocktail recipes for the Matthew Project which helps people across Norfolk and Suffolk.
The Matthew Project wants people to raise money by participating in Alcohol Concern's national Dry January campaign.
The campaign splits sponsorship money between Alcohol Concern and the people's chosen charity, which the Matthew Project wants to become.
Matthew Project CEO, Paul Martin, said: 'We're having some fun with Norfolk Mocktail recipes, raising money through Dry January and spreading an important message.
'We're keen that people feel Dry January is a positive and healthy time. We think they should still go out to eat and enjoy themselves – and the submitted recipes show it's easily possible to cut the spirits and keep wonderful tastes.'
Creative concoctions have also been donated by Great British Menu chef and Norwich's Benedicts restaurant owner Richard Bainbridge, owner of Blue Joanna on Unthank Road in Norwich, Ecky Limon, and Norwich's Dynamic Fitness owner Ross Lenton.
