I was on klonopin for sleep disorder. Anxiety and PTSD. My dr didn't explain but I guess it is medical conditions like seizures that r too dangerous. I did have my first panic attack after years of klonopin when I was in my 2 weeks after last klonopin dose. Dr added hydroxyzine, antihistamine used for alcohol withdrawals. I have increased anxiety and needed to start my mindfulness, meditation, and crocheting to keep brain busy. It has helped. Yes, it is scary!! I did work thru it but it was horrible. I am trying to work thru without medication. Its easier to take pill, but i am determined to stop klonopin. My memory issues are more serious to me and my family, and I am taking it one day at a time. I will be giving myself grace, and try to keep off klonopin. My journey is hard, but it is the direction I chose. Keep trying.
