Hello Poohbah...
I had a dependency to Xanax about 10 years ago, mainly because it worked so well that I couldn't let go of them... From the first day that doctor prescribed it to me I never increased the dose (I was convinced that I would not be addicted to them if I had some kind of control)... But, it came to a point that the dose was not enough, so as a maverick I decided to go cold turkey-mate, it was a horrific experience. To get to the point, if you think that you will be able to control the usage of Xanax, go for it, but I would suggest therapies vs. addictive chemicals...
