"i was given xanax in the hospital when people at work thought i was having a heart attack. my anxiety shot up so bad, my heart rate was 170. been on 2 mg a day ever since (this happen 2 months ago). i only take 1 1/2 mg a day &amp; it works for me.  i feel like i have control of my life again.  i have heard stories &amp; seen people on it who over take it but if you take it as prescribed,  it works."
