No tea. No coffee. No fizzy drinks. No wine. No beer. No orange juice - are you up for a challenge?
The RNLI is challenging people to give up all drinks except water for 10 days for the H2Only challenge to raise funds for the lifesaving charity. Two local women have accepted the challenge and are calling on others to follow their lead.
Helen Christie and her sister Kerry Miller from Portrush watched their brother Nick respond to many calls for help during his time as a volunteer lifeboat crewmember with Portrush RNLI.
The H2Only challenge runs from 5pm on Tuesday 2 June to 5pm on Friday 12 June, with participants giving up the drinks they love for 10 long days and drinking nothing but water throughout the challenge.
Participants will be able to download the free H2Only app from Google Play and the Apple App Store from Tuesday 26 May.
