That would sink a lot of your worries about weight gain and binge drinking as you would know exactly when to put the cup down.

Called Vessyl, the "smart" cup can be asked to display a particular set of data to aid you achieve certain goals, such as losing weight or regulating caffeine.
Made of a glass-like material, the cup holds 385 ml of liquid.

The cup can measure the caffeine levels inside a drink that has been poured into it, in addition to the sugar, protein, calories and fat inside a drink.

It will begin shipping in early 2015, media reports said.
