Halevi: I haven’t seen the Darkei Moshe, but the Rema in Shulchan Aruch is clear that the kiyum of ad delo yoda is the sleeping, not the drinking?
What is “the kiyum of ad d’lo yoda”? Ad d’lo yoda is either a shiur or a p’tur. It is not the mitzvah. The Rema in Shulchan Aruch is perfectly clear as well. He says וי”א דאין צריך להשתכר כ”כ. He is limiting the amount of drunknness required, not eliminating the chiyuv to be somewhat intoxicated.
