I just wanted to add quickly, and you may already know this, that depression can be a side effect of the long term use of any benzo. My pdoc told me this when I told him my depression had been worsening at one point. He didn't suggest I stop but just cut own a bit or not take it as regularly. It's annoying but it seems like when something works in one respect it can have adverse affects in another. I remember my doctor telling me this and that you just have to pick your poison
