Clonazepam
"So, I used to have pretty debilitating anxiety. When I finally went to my doctor, he diagnosed me with a panic disorder and gave me clonazopam. Like any other drug of this sort, how responsible you are with medicine should determine if you take this or not. He gave to to me and told me to take it once at night when I went to bed, and then as needed if I was having a panic attack. This made me a little bit drowsy in the morning, so I stopped taking it at night and switched to just as needed which he said was fine. I have 1mg tablets, and take 1/2 at a time. I TRULY TAKE THIS AS NEEDED, and have never needed to increase my dose. At sight of a panic attack (maybe 3x a month now, used to be everyday) I take one, and it goes away."
