oomis, We’re going to have to agree to disagree. You and your like-minded will minimize your drinking on Purim, whilst we and all our like-minded Yidden will follow in the footsteps of our Zeida’s and as codified in the Seforim and will drink Ad D’Lo Yoda.
The Gemora (Megillah 7b) quotes Rovo that “one is obligated liv’sumi [Rashi – to become intoxicated with wine] on Purim ad d’loi yoda [until one cannot distinguish] between ‘cursed is Homon’ and ‘blessed is Mordechai'”. Shulchan Aruch (OC 695:2) and Remo, rule in accordance with Rovo, and state that this is an obligation. The Bach states that according to the Tur one is literally required to become so intoxicated on Purim that one is unable to distinguish any difference between ‘cursed is Homon’ and ‘blessed is Mordechai’. The Shelo Hakodoish and Chacham Tzvi are said to have fulfilled Rovo’s ruling literally. The Shelo Hakodoish is also quoted as stating that one who is frail by nature is exempt from becoming intoxicated – the implication being that one who is fit and healthy is obligated to become intoxicated. The Rambam (Hilchos Megilla 2:15) rules that one should take wine to the stage that one becomes intoxicated and falls asleep. The Sfas Emes explains that the obligation of ad d’lo yoda is a requirement to rejoice and drink continually.
