Since I stay up on Schowu’os nite, I cannot emulate this deed on Erev Schowu’os, hence I make it my business to sleep on Erev Schowu’os, to avoid a Chashash of acting out Schowu’oth nite prior to Kabolas Schowu’oth.
Likewise I make it my business not to consume cheesecake on Erev Schowu’oth, so as not to emulate my Seudas Leil Schowu’oth, & I can then heartily consume my cheesecake, after which I go to Tikun Leil Schowu’oth.
By the way:- “Ein ben Erev Schowu’oth Chechal Bechol Oh sheChal BeShabbos”, vis a vis these practices of mine.
