If you're down to your last chocolate, it's not all bad news - it'll probably taste better than any of the previous ones, a study has found.
Psychologists discovered that knowing something is about to end makes us enjoy it all the more.
The US researchers fed men and women five small chocolates of different flavours and asked them to rate their enjoyment of each as they ate it.
The flavours were given in different orders and some were told when they were on their last chocolate, while others were not given any warning.
Those that were pre-warned found the last sweet much more tasty than the others, the journal Psychological Science reports. Asked which chocolate was their favourite, those who knew when they were on their last chocolate plumped for that one 66 per cent of the time.
