Changeling's Neurotox Is Now Lethal?

[Embolism]

And I just saw that Cogwerks mentioned sleep toxin. I wasn't aware that was even still in, given that sedatives were removed from medilockers.

If it's like the old sleep toxin though, I don't think that produces yawning (and maybe snoring)? Yawning used to only happen with somnambutril I'm pretty sure?
