Buspirone
"I experienced my very first Anxiety attack three months ago, stemming from stress from work and eventually from fear of dying (provoked by the symptoms of the attacks). I began to fear nights, because they occurred at night, preventing me from properly sleep. I went two months without seeking medical help, until I did. I was diagnosed with Generalized Anxiety Disorder. They prescribed me BuSpar/Busporine; I've been on it for a little over a month now (7.5m.g. twice a day) and OH MY GOSH, it saved my life. I haven't had an anxiety attack since the first day I began taking it! The first week, the only side effects I got were feeling groggy in the morning, but at night when you take it they do help you immensely to fall asleep."
