It's been years since then. At the end of the day it's FAFO.

That fainting episode wouldn't have been prevented with a guide unless they followed me into the bathroom, since for some reason the smell is what caused me to faint. (I found this out during the second time when going near the bathroom made me feel fainty -- I am glad I figured out what it was so that I could avoid it. It would've sucked to conclude that I can't have psilocybin at all, or something)

I will actually end up visiting the NL for other reasons eventually, so I might look into magic truffles :)
