I went from 8 x .5 to 1 x .5 over a few years and from .5 to 0 in a few months so that part of it was fine. I also saw a therapist during this time but what made the difference was doing anapana/vipassana. Now I'm benzo free and largely anxiety free. It took a while for it to dawn on me that I was facing life without benzos and wasn't feeling the continuous anxiety I'd become so used to. If I feel a moment of anxiety I just use meditation to deal with it. It passes quickly. Another critical factor for me has been diet. I found that getting to a good weight and cutting out wheat and dairy has helped a lot. I don't know why I just accept it does. Perhaps there is something like that you can try. My kids are out of the nest and I survived.
