Please keep us updated on his progress and how he does through withdrawal/PAWS. I would love to know what his final diagnosis is in a year or so. Two years is a long time on that stuff, he actually sounds pretty lucid to be hitting it that hard for so long. I lost my sanity pretty early on, and didn't have the where-with-all to even notice any withdrawal or PAWS getting off it, and my experience wouldn't be valid anyway as I was going through benzo withdrawal from quitting cold turkey after using daily for ten years (literally couldn't remember my name at times).
