Ive been prescribed plenty of benzos. Xanax, ativan, klonopin, valium, and restoril (temazepam)
Personally I haven't ever gotten a nice high off any of them. Ive tried high doses. Xanax makes me very relaxed but pretty tired. Klonopin even at 5mg or so doesn't do a thing, same with ativan. Valium helps me a ton with anxiety but not.in a rrecreational way and doesn't help me.sleep.
Recently ive had horrible insomnia. Ill go 2 or 3 nights with 0 sleep. For this purpose I was given temazepam 30mg. This immediately has become my favorite. At 60mg it puts me in a very relaxed outgoing state. It doesn't make me super tired either, it just allows me to be so relaxed that I can sleep when I want.
As far as how to take it. Just orally is the way to go. With near 100% bioavailabilty there's no need for any other route of administration.
As many have said, benzos effect each differently. For me temazepam is the only one I consider to have rec value. That's just my opinion. My body chemistry Apparently does well with it.
Forgot to mention rohypnol. I do find that to be euphoric actually. But getting it is not worth it.
