I have had panic attack for about 35 yrs and I have tried different meds over the years. I found that Klonopin is the only thing that works for me and I have been on them for over 10 yrs. I was so bad my throat would close up and I couldn’t even swallow water. I would choke on it. The only thing that has helped me is the Klonopin.Feel free to e-mail me if you want to chat about this
