Clonazepam
"Been on Klonopin for 3 years. Lifesaver, have panic attacks due to congenital heart defect. They label it chronic life long health condition always feeling panic that something drastic was going to happen. Klonopin gave me back my life. Take 0.5mg in the morning and 2 mg at night. Wonderful. Hope this helps. I've tried it all."
