anxiety
"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 & it works for me.  I feel like I have control of my life again.  I have heard stories & seen people on it who over take it but if you take it as prescribed,  it works."
