If Valium is tolerated, most docs will suggest a Valium taper, since it is the easiest. If you can talk about easy in these situations. Some people have an antianxiety effect from some neuroleptics or antihistamines, so adding one through the taper can be helpful, if you're the kind to tolerate those meds. I can't take them, they make me worse..

I've noticed that some people only build tolerance after hitting a certain mg, which means as long as they stay on a low dosage, they don't need more. That of course does not go for all people, but some are like that. So it is sometimes possible to regain help from a benzo after a taper from a high dosage. But then of course one must be responsible and really not take more.
