If you want to cut down on your drinking without sacrificing nights out, the answer could be straight forward.
Research shows that beer is drunk much more slowly from a straight-sided glass than from a curved one.
In fact, it takes almost twice as long to enjoy a glassful.
The finding means those who want to enjoy a night out without suffering a hangover the next day may do well to avoid the curved beer glasses that are often used in bars.
Social drinkers taking part in the Bristol University study were given a glass of beer or one of lemonade and told to drink it while they watched a nature documentary.
