I have found that I can take half of one of my .5 Xanax and get the relief I need. I have a history of addiction (30 years sober) and I see a p-doc who specializes in addictions. He is convinced that I am safe at my current dose. I just take it only when needed, and start with a half dose and only take the other half if needed-which is almost never. It works really well for anxiety and for falling asleep.
