If you can avoid benzos, that would be best. It took me a year to taper off clonazepam and it SUCKED.

I am on propranolol. I take it twice daily but I think it can be taken as a prn. There's also buspirone (Buspar); that one I've always taken twice daily and don't think it is usually a prn.

I have hydroxyzine to take as needed; it's much safer to take than a benzo. In the past, I was on lose dose Seroquel, but if the hydroxyzine makes you sleepy, the Seroquel would probably knock you out even at a low dose. The Seroquel helped me more than the hydroxyzine does. What dose hydroxyzine do you take? Would it be possible to take 1/2 a pill and see if that would help without making you sleepy?

Of course, none of these meds are as effective as benzos for me, but they generally do take the edge off.

And as the previous poster suggested there is exercise, deep breathing, meditation. You should also google grounding for anxiety. Grounding work s a treat for me while I'm in the moment and doing the grounding exercise, but when I stop, the panic/anxiety usually returns. Other people have better success with grounding; you just have to try some grounding exercises and see how it works for you; there are lots of different methods of grounding. For me, what works best is closing my eyes while touching something cold, like a glass of ice water and just focusing solely on the temperature I feel with my fingers. But there are other grounding exercises like the 5-4-3-2-1 technique.
