Sorry Jothar but it is quite famous that Rav Yisroel Salanter and his talmidim would be stone drunk the entire Purim and sober up as soon as night fell.
Additionally I was told by “alte mirrers” that on Purim all the bochrim drank.
While it is true Rav Aaron Kotler zt’l did not drink on Purim neither did he drink the entire year for kiddush he drank the bare minimum to be yotze and Rav Shneur zt’l used to become quite shikur on Purim as Rav Malkiel Kotler shlita does as well.
Interestingly I was told by a talmid of Rav Aron zt’l that Rav Shneur was extremely shy and would not say any Torah of his own the whole year but when Purim time came and he was shikur he would all of a sudden become a “mayin hamisgaber”
