Very hard to say without context, but in my experience some psychiatrists aren't anti-benzo so much as anti-xanax. Xanax has a very short half-life relative to others, hence TID dosing if you're using it for consistent anxiety control as opposed to PRN; it's also much more likely to cause euphoria when taken in recreational doses, thereby increasing the likelihood of addiction/dependence; and it's also just an unpleasant medication to wean off of because of the short half-life. You're at a greater risk of complication (seizure, DT's) during a med taper as compared to other benzos.
