I'm similar -- thankfully, when I panic I can frequently get through it without taking a benzo, but I do have clonazepam on hand for the situations where it might be very useful.

There are times where I would've likely made poor decisions during an acute panic attack that was aborted quickly by benzos. The ability to say "stop now" -- hell, even the security of know there's a way to say "stop now" -- is important to coping with anxiety.
