But yes, if you don’t have any guilty feeling, you absolutely are obligated to sleep in a Sukkah.
Which is (almost?) everyone, yet nobody sleeps in the sukkah.
So I asked a chossid Chabad this, and he said that he’s mitztaer that he’s not mitztaer. So I told him to be mitztaer in the sukkah, since the sukkah isn’t what’s causing the tzaar. It’s an offene Rashi.
Total disregard for the actual halachic process. Sad.
