Panic Disorde
"I started taking Xanax in 1992 after having a  heart catheter that went wrong. I went into V Tach after that I suffered from arrhythmia daily and panic attacks, ending up in the hospital a few times.. First the arrhythmia starts which brings on panic attacks. I realize now this is all PTSD. My new internist put me on Xanax at. 025mg which had little results then upped to 0.50mg which I take one twice a day. 24 years later I&#039;m still on it taking same dosage. Tried going off a few times unsuccessfully. New doctor lowered it to one day. Hoping for the best."
