Gonna go out on a limb and say no.
Having been slipped date rape drugs, I was keenly aware that something was going wrong up until I couldn't form new memories. Apparently I was still talking and acting kinda normal except I kept repeating myself. I couldn't form new memories and eventually blacked out. Thankfully some friends took me home. I couldn't even remember how to get into the car but I was carrying on weird conversations. Is it arguable that I was unconscious, while walking and talking? Maybe...
It's an interesting argument but I think it falls short.
