With Christmas ever closer, now more than ever the drinking habits of those working in the capital can get out of hand.
Joy talks through recent findings which worryingly point to a trend of increased heavy drinking among women - and explains how retailers' promotions aren't helping.
She tells London Live that the number of retired women who have checked in with a drink problem has risen sharply, and now one in ten women over 65 admit to difficulties with alcoholism.
Surveys also show professional women drink twice as much as those in other jobs.
Joy explains how drinking problems often go unnoticed because of London’s working culture, where afterwork drinks can too often run long into the night without anyone thinking anything is wrong.
As Christmas is typically a boozy time for many, Joy also offers her alternative nights out for those who want fun but not a hangover.
