Well there is Propranolol as Nammu said.

Also....

Buspar

Gabapentin

Visteral ( altho for some people this is too sedating)

And some people that can tolerate a SSRI's ( not everyone with Bipolar can take as it can bring on a Manic episode)

Many Pdoc's are getting people off Benzo's as there are some studies that show it can cause early forms of Dementia, but I also think that Big pharma has a variety of brand new shiny medications coming down the pipeline to replace them and also since they will be new they will be expensive.

My fear is that if Medical providers do take people off Benzos that many will turn to Alcohol and Street drugs for some relief which in my opinion is much worse than taking a Benzo.
