We have s-zopiclone (eszopiclone, I guess they think removing the dash and spelling out the "es" makes it sound better or something, I don't get it), it's branded as Lunesta. And of course, zolpidem (Ambien).
True story, I once went in to my college's doctor services, trying to seek drugs. I told him I had a bad cough and that DXM made me feel awful. He had all this pharma advertising up on the walls about Ambien. So I was like, hmm, good idea, perhaps I also have trouble sleeping?? I asked him about it and he was like (and I quote) "bro, ambien is for little old ladies who can't sleep. Are you a little old lady, bro?" Of course I said no... but he did script me a bottle of DAT LEAN (codeine/promethazine). I was ecstatic. Went home, figured I was in for a treat. Took twice the prescribed dose... got sleepy as fuck, passed out.
Moral of the story? Don't believe rap videos. Lean aint shit, makes you lean so far over you're horizontal, and sleeping. Tried to catch a good high off of that bottle a few times, nope, never happened. Taking a couple of tylenol 3s was much better,
