If you're like most people, the last few weeks have been an orgy of holiday food and drink.

However, if you've officially had too much, a Dry January might be just the ticket, and a new study shows it has more benefits than simply getting an overdue "Thank you" from your overtaxed liver.

According to researchers from the University of Sussex, abstaining for a month can help you drop weight, sleep better, and save money -- and it can stop you from drinking too much in the long run.

The simple act of taking a month off alcohol helps people drink less in the long term: by August, people are reporting one extra dry day per week.

There are also considerable immediate benefits: Nine in ten people save money, seven in ten sleep better and three in five lose weight,” says the study's lead author, Dr. Richard de Visser, in a media release.
