be up with the lark
To be awake, out of bed, and active at a particularly early hour of the morning. (Sometimes written as "up with the larks.") I don't know how he does it, but my husband is up with the lark every single morning. I won't have another pint, thanks. I have to be up with the larks tomorrow, so I'd better head home soon.
