I didn't get rapey vibes from this at all. It sounds like he's anticipating the comedown from cocaine. The "shake, rattle, and roll" is the perfect description of that anxiety. He's in a quiet, tired headspace as the dawn approaches ("cracks in blackout blinds"), and this person is still high and chatty. I don't know, it definitely recalls that moment of disappointment when you know the nite is ending and you're about to come down ("don't get that sinking feeling, don't fall apart"). He's wondering if this person (who he's done this with before) will pour him a drink to ease the pain of it before he has to leave.
