Citalopram
"I was on Cymbalta for years, but my insurance stopped paying for it.  I have a high stress job and it got so bad that I couldn't focus at work and when Sunday night came, I started tensing up and started having panic attacks again and would wake up in the middle of the night with them.  I started taking 20mg Citolopram for about a month and it was working great, but before 24 hours was up to take my next dose, I started having break-throughs and now on 40mg daily.  Just started with the higher dose today; we'll see how it goes. "
