Purim and drinking

Thi is according to R doniel Nuestadt (or however he spells his name) in his weekly torah paper he sends out.
If your father tells you you cant drink on Purim, do you listen to him.
Ans- NO since ad de'lo yada is a mitzvah, you dont have to listen to your father when he tells you not to do a mitzvah. Steve (and dad) had a problem with this. Listening to your father is in the Torah while drinking isnt...but hey thats what he says...He does bring down r S.Z. Auerbach who disagrees with him.
On shabbos we ate at the yosef and rachal seligsons for Lunch, and yosef brough this up, and opened a sefer, but i cant remember whose it was. Anyway the rabbi in the book said that the only time you can use sleep to get around ad de'lo yada, is when your slep is alcohol induced, in other words you must pass out then your sleep is good. Again some rabbis disagreed with him as well.
thats that for now
