if you ever tasted benzo's im not sure buspirone will work, it probably wouldnt for me, un less someone tells me hppd only goes away when your quit them, so you can heal.. i still think i can heal while being on benzo's. While there is a little voice in me is telling, dude you are screwed, you have a life sentence.
I would quit the benzo's and go for buspirone, as an alternative for a benzo. Its going to be hard
