I did state that it's "sedating" in that it's a general anaesthetic - I guess that's a slippery use of the term "sedative" but a large dose of ketamine would literally floor any and everybody, full stop, I'm sure we can agree to that? Of course whether the ensuing experience is considered sedating is entirely up to the user.
I happen to fall in that happy category of people who can K-hole to get to sleep after an excessive stim binge.
....Or am I barking completely up the wrong tree?
Well it may be able to floor you if you take a large dose, but this is entirely different from sleeping. Even those under medical anaesthesia from ketamine are not properly 'asleep'. In fact, there is a good indication they are very much awake and aware, just completely and utterly in another world. If you've ever watched one of those horrible documentaries about cosmetic surgery (I don't watch TV anymore, but back in the day...) you may have noticed that the patient is still responsive to the physical assault of the surgeon, making disturbing groaning noises and all sorts, all the while under ketamine anaesthesia.
I would bet that if you hooked up an EEG to a person who has taken a hole or super-hole (anaesthetic) dose of a dissociative, it would show something very different from the brainwaves patterns and cycles that you would see under normal nocturnal conditions.
With psychedelics such as tryps, phens, and lysergamides, an EEG taken during one of those "passed out" sections of a heavy trip would also show something different, though I would expect it to have some of the more familiar patterns seen during REM sleep. But I would hesitate to call it sleep. More like a nod.

LSA gets very lethargic and sleepy to me near the tail end, I actually passed out at t + 9hr on one trip, while still tripping.
A similar thing happened to me during one of my most intense LSA trips. It's hard to gauge in such moments how long you've been out for, because the moment of passed-outness seems to blend seamlessly in to the rest of the experience. And that moment also feels timeless whilst you're in it, like you could have been there for seconds, or years.
