I find ambien loses its effects if taken too many times.
Breaks keeps the experience nice and fresh, not that I intentionally stay awake, you understand.

To me, it has, in low doses, similarities to ketamine. The floaty wobbliness, and oddness, and euphoria.
Everything seems to wave, and many times, I can feel a presence, when there is none, apparently common on ambien.
Regular snorting would scare me, I would feel like I am playing with fire.
Curiosity, however, has occasioned me to experiment with this novel way.
I did it when I was coming down off an E, and all I can say is "far out, man" twas a bit scatty though.
The ambien I had was a 5mg, circular, white pill, and when ground into snorting powder, there were flakes, which was the thin, outer coating of the pill. These would not rack up to a talcum consistancy.
A wee bit uncomfortable, but only momentarily.
I have yet to try one, up the hooter, on its own, with no other drugs.
