If you're going out on a first date for Valentine's Day tomorrow, ease up on the drink - you might say something you'll regret or even worse, post it on Facebook.
A survey of around 200 people aged 18 to 55 found that one in five people ended up saying or doing things they regretted on a first date because they had too much to drink.
The survey was done by Research New Zealand for the NZ Drug Foundation.
It comes as the organisation is running its latest campaign, called FebFast, in which people are encouraged to give up alcohol this month to raise money for young people affected by drugs and alcohol.
Of those surveyed, 30 per cent said they had said things on a first date which they later regretted, while 22 per cent said they had done things on a first date that they later kicked themselves for.
