I definitely should have touched on vomiting re: noise. It doesn't have the rep for it SN does (i.e. practical guarantee) but the risk is real. But having thoroughly researched meto I can say it sounds scary as shit if you're one of the unlucky ones to catch the "rare" side effects, so I get the apprehension there. I'm trying to source domperidone for this very reason.
Also, OP, time is huge. I know consensus is N has you out in a few hours with ample dosage, but outliers happen even then and minimum 24 is recommended. I again have to stress the avg AS client - old or sickly - and how that likely skews time data. 11 is a solid window if consistent and reliable, but there's just a lot of reasons why a shared roof is hard to recommend for ctb. Parents are just going to be more high alert in general than regular housemates owing to that whole dynamic. Mom's spidey sense and all. I'd look into any option you can to be elsewhere. Again I'm sure most of this has occurred to you but, "it be like that"
