panic disorde
"Approximately twenty years ago, I was taken by ambulance twice and once by car to ER where they gave me something that calmed me.  It was similar to a seizure. Nothing ever triggered these attacks.  It just came upon me very fast. I was enjoying my career and life; I'm very social.  My doctor finally sent me to a Psychologist and he diagnosed me with panic attacks. There was a name for this!!  I was prescribed something similar to Klonopin and when Klonopin came on the market, he prescribed 0.5mg twice a day.  I have had no adverse side effects, only positive.  I have never had another panic attack and do not plan to ever stop taking Klonopin. I am the same person I was and live life to the fullest in a new phase of 'early retirement'!!"
