I think that anyone that survives this is a bit like humpty dumpty - all of the crazy glue in the world isn't going to find or position every little piece back to where it was. I don't think that I will ever be the same person I was. I hate the vocabulary that I have had to acquire, the optimism that died, the stress on my marriage, finances, etc. Just the mortality thing alone keeps me up a lot at night. Then there's the second thoughts about virtually everything and days that I just can't get it together. And I'm one of the "lucky" ones. I'm still on this side of the grass. I was Dx'd with PTSD after the shouting was over but I refused to take the Prozac. I'm still trying to figure out why I was spared... (at least for now). Then there's the guilt. I whine about my minor little issues when many here are really suffering. I can relate to feeling out of body on some days and other's I'm focused like a laser beam.

And yes, Zanax is a pretty potent drug and there is a long withdrawal from it. See:
