Volvie, I disagree. Nobody SHOULD do excessive drinking. I define excessive drinking as drinking which causes the drinker to be mevatel mitzvos asey deoraysah. Volvie, there is also no shita to drink the night before (when many bochurim get drunk). Volvie, do you agree that any bochur who is mevatel mitzvos asey deoraysah is NOT being makayem a mitzvah, as the mitzvah derabanan of drinking on Purim is NOT doche mitzvos deoraysah?
I drink plenty on Purim- Grey Goose, as per the psak of my rav that any mashkeh is acceptable. but I am also mekayem the mitzvos deoraysah, as per the mishna brurah. Those who don’t are drinking excessively. Those who drink themselves to the point of alcohol poisoning are also doing an aveirah.
