Dry January: 'Do I need alcohol every time I go out?'
Many people are taking part in "Dry January" in an effort to reduce their alcohol intake and kickstart a healthier new year.
Dr Joe McAvoy, a GP in Londonderry, said it was an opportunity for people to reassess their relationship with alcohol following weeks of family gatherings and parties over Christmas.
BBC News NI asked people in the city for their thoughts on whether they were taking part and what benefits it can bring.
