if you're not suicidal, drug addicted, and if drug-drug interactions are OK and the psych is a-OK...now and then,t he barbiturates can be used. phenobarbital is still used, every now and then, although i hear its nasty stuff (long acting, drug-drug interactions, not the most pleasant stuff ever). there are a couple of other not as long acting barbiturates on the market, some are reasonably priced (i guess that means at least some people are taking them for sleep, anxiety, etc.) and others are specialty drugs (I guess?), so there's a crazy insane mark up, which...would make insurance coverage an issue, especially since many plans frown upon Rx sedatives, in general.
xyrem (Rx GHB) is used as part of treatment in narcolepsy...I've read 2nd hand accounts of people (I'm guessing with excellent coverage and doctors who saw potential for help...) using it in psych indications.
other than that, I have 0 guesses as to what might potentially be helpful. :-(
