Xanax Not Good for Long Term Treatment of Anxiety

Xanax is not a good medication for the long term treatment of anxiety for the reasons outlined in you question.  First, people develop tolerance.  Secondly, because Xanax has a relatively short half life, many patients experience break-through anxiety.  When this occurs they take more Xanax, more often to less and less effect.  The best thing you can do is to come clean with your doctor(s) and work with them to come up with a safe and effective detox plan.  You should not try to manage this on your own.
