Be drunk

Do you mean the persona of the speaker in the poem?

Yes

The speaker's persona seems introspective and existential. Baudelaire asserts that one must be continually drunk without pause both in a literal and metaphorical sense. You can “take your pick”: become drunk “on wine”, or drunk “on poetry, on virtue.” The speaker seems happy to be imparting information about man's eternal struggle with time and the inevitable labours of life.
