In my opinion, you will only find out which benzo would be best for you in vivo, or in the field. At the very least, the benzo experience that I have is what would generate any advice I'd give, and I think the same would go for yourself. I also agree with other peeps that in my experience as well as opinion, benzos for anything but sleep or mind-splitting anxiety is generally a profoundly counterproductive idea. Instead of a drug you might consider just making a very extensive effort to be real honest all the time and not give a fuck about much else.
That being said (and, being on some prescribed Temazepam for sleep at the moment), I'd look into opiods, myself. Or a low dose of diazepam/valium or something long acting but not too impairing/hypnotic, maybe klonopin/clonazepam? At the very least, something you wouldn't have to worry about wearing off on you for a while...
Just read your post on the clonazepam actually.. I'd personally try at the .25 or .5 mg range, see if you can get away with it. That's the mindset I've taken with benzos and, coupled with, you cannot get away with drinking and taking benzos, have kept my ass out of some shit.
I would not recommend Temazepam at all, unless you know some wild girls...
