I had been on clonazepam , just not at this dose, for about 17 yrs after anxiety attacks after I had back surgery. My np kept telling me I was in withdrawal. Would go away after med got out of my system. I didn't get better. Got worse. Didn't know what withdrawal was. Finally diagnosed with akathisia. Put on regimen of propanalol 10 mg 3x daily, trileptal 150mg 2x daily,
