Social media is proving a popular choice amongst those giving things up.
A church in Galway is offering drive-thru ashes for its parishioners this Ash Wednesday.
The parish of Glenamaddy is offering the service to people who don't have time to get out their car to receive the blessing.
Meanwhile, today marks the start of Lent with social media, alcohol, chocolate and meat the most popular things to give up for the next 40 days.
Getting fit is also a popular commitment, but Abbeyleix parish priest Father Paddy Byrne, says it's important to do things for others too:
