"i suffer from panic attacks that occur after i go to sleep.  i wake up about an hour or so after i fall asleep (i don&#039;t have trouble falling asleep) freaking out.  my heart is racing, i am terrified and i feel like i will go crazy before it stops.  they are so scary because no matter how many times i have suffered through them, i am always sure i am dying when i have one.  previously i was given other medications like buspar or paxil, but i didn&#039;t tolerate them very well and they did not stop the attacks - only slowed them down.  once i was prescribed xanax i noticed that the medication would actually stop a panic attack in its tracks, which was a miracle.  the medication has almost completely stopped the attacks - but not 100 %."
