I was on clonazapam for 14 years..slowly weaned my self off. Was off for 3 months doing great. I started having ringing in my ears. ENT Doc put me on 0.25 MG of xanax he thought I was gritting my teeth. Now my panic attacks are back, can't sleep, freezing, shaky etc. Needless to say i am now back on clonazapam 1/2 -0.5 What could cause this? Please help I'm desperate! ! Could this be a bad reaction? I even turned red in the face, hands and legs! I'm dying!
