I think I've got a word in mind but it's not coming to me. The sentence in question revolves around an unconscious character's head "lolling from side to side" as he's carried across a room. I was going to say his head was "lolling limply from side to side," but I'm trying to think of a...more descriptive adverb. I'm looking for something that captures the essence of his unresponsiveness. The scene's POV character is extremely concerned about this character, and the way his head is moving makes her afraid he's going to die.
"Limply" works, but I'd just hoped to find something more specific, and I'm drawing a blank. Does anyone have any ideas based on the above description?
