I did not. I have been taking 3mg for months now, though I recently started to suspect it's too much, and dropped down to 1.5mg. If you are taking it at bedtime, rather than a couple of hours before, that can cause it to fail to be effective. I haven't seen anything to suggest dependency is an issue, and, if I miss a dose (forget to take it until too late), I have reverted to my old sleeping pattern, rather than anything worse. No increased onset insomnia or anything like that.
