What's the idiomatic way of describing the fact that someone has had some alcohol?
For example, a husband is coming back home from work and starts talking to his wife. He is not drunk, so he speaks and acts just as usual. However, from the scent coming from him she understands that he had some at work. So she says, "I see you have already ________________!"
What would put in the blank here? (Any part of speech and any number of words in the blank are okay, but only one verb - if that's possible and idiomatic - is preferred).
