Mik5: Some Poskim hold there might be a Mitzvah last night but it’s a minority. If you hold like the Rishonim who say that the Mitzvah is Davka B’Seudah then it wouldn’t matter what or how much you eat or drink as long as you have the Seudah. If you hold there is a Mitzvah for everything you eat all day then it should apply to drinking as well. (If I recall correctly the Gemara uses the Lashon of Kol Ha’ochel V’shoseh…”)
