Buspar can work very well for some people. It is not a benzo and I suspect your physician's assistant doesn't have a blank RX to write an order for benzos.
I would have to look back to see what your new med is? My Psy Dr. is very strict about writing RX for benzos.
I do use Buspar as part of my cocktail but others use it as a stand alone medication.
Good luck and know we care,
