Do couples who drink together stay together? Recent research from New Zealand suggests that women who regularly drink alcohol with their partner are happier in the relationship than those who drink without their partner. Imbibing together often means socialising together, which may lead to increased satisfaction, says study author 
Jessica Meiklejohn. Another factor: similar drinking habits could indicate overall compatibility. Don’t drain a 
bottle, though: the study also found that relationship happiness decreases if one or both partners are heavy 
drinkers or if one drinks more than the other.
