I took Xanax for over 10 years and I recently stopped. Memory loss was the reason. I had my last Xanax May 20, 2006. So far I am feeling pretty good but the old problem of insomnia from 10 years ago is back. VERBAL RECALL difficulty is the #1 symptom of long term Xanax usage (I still support Xanax usage by the way). Once my boss asked me for my address so he could pick me up for a trip and I couldn't remember it!
But my memory has gotten much better during the past couple of months. I have a private office at work so when I get panic attacks I can just wait for it to pass without much embarrassment. When I can sleep, everything is pretty much fine (so far...)
