Know your units

Adding up your units can be tricky at first, but once you know how many units a drink contains, you can keep track of what you’re consuming. A large glass of wine, for instance, can contain around 3 units. In one evening, that can quickly add up to a lot more than you intended to drink. 

What's a unit?
