Same here with klonopin/clonazepam . I take .5mg max which is generally the starting dose, and very, very sparingly - like .5mg every few months max.

Benzos can absolutely decimate anxiety reliably - and half of my panic is the fear of not being able to control a panic attack (thus the self-feedback loop into panic). The amount I take only takes the edge off which is all I need, just knowing I have it is such a massive help at preventing panic attacks it's crazy.
