“If the rabbeim (and chassidim) wore makpid ad kedei chach, to not even drink a little sip of water outside the sukkah even if it raining, and even on shmini atzeres, why wouldn’t they be makpid on sleeping in the sukkah?”
I’m confused, are you switching to our side on the sleeping in the Sukkah issue now? I’ve read your question several times, and it seems like you’re making exactly our point. By the way, non-Chabad Chassidim don’t eat in the Sukkah on Shmini Atzeres. I’m not saying that’s right or wrong, just “fact-checking.”
