When you decide to give up alcohol for a month, it's natural to worry that your resolve won't stand up to the test.
But for women embarking on dry January, it's not their own ability for self-restraint they have to worry about - it's their partner's.
Men are a bad influence on their other halves when it comes to alcohol consumption, experts say. They can even sabotage a woman's efforts by suggesting they drink more.
Researchers found that 29 per cent of women confessed they would drink far less if it wasn't for their partner. This is almost twice the number of men - 16 per cent - who said their alcohol intake would be lower if they were single.
A third of men admitted they actually encourage their other halves to have just one more drink - even when they've had enough.
