Never had one even bring it up, although I've taken it before as a sleeping pill. I hadn't realized onset is as quick as Xanax, and the effect size looks good, but it's never done very much for me for anxiety.
Edit: Granted, falling asleep is not really conducive to being able to work. So I imagine there a number of people where "it made me fall asleep, but I can't do my job like that" is a non-starter, and short-term benzos is the only way forward.
