BS”D
Everyone is different, but for me the mashke kiddush on Shabbos and Yom Tov (which indeed is not the proper minhag even and especially for us in Chabad!) prevents me from wanting to go near alcohol during the week, even at simchas except those of people who I am very close with and where I must make lechaim.
The buzz I get is fine for resting on Shabbos, and since I eat a lot more on Shabbos and YT than I do during the week the ethanol gets absorbed fast and the buzz is all over and done with fast especially if I have a chance to put my head down between kiddush and Mincha. Since I know full well I don’t want that buzz or any drowsiness during the week I don’t touch the stuff and haven’t even kept any mashke at home for anything but cooking in a long time.
