Xanax
"I didn't realize all the stress that I had been under. I'd actually experienced a panic attack for the first time at 23 while I was driving home from college.  I thought that I was going to die.  I was frightened by the entire experience.  I went to my doctor who prescribed me with the lowest dose of Xanax in addition to 20mg Prozac.  About three months later my doctor decided to increase my Prozac to 30mg.  I haven't needed Xanax for months, but I keep it on me where ever I go.  Xanax is so fast acting.  It calms my nerves instantly."
