Sertraline
generalized anxiety disorde
"I was on Zoloft in my early 20s, but never found it very effective them. Fast-forward 15  years and every other anti-dep med later, my Celexa pooped out on me and I started having daily anxiety and panic attacks. 

It took nearly eight weeks for me to feel any positive effects from the drug. The start-up side effects were terrible - I was sick for weeks. However, when I was switched to Zoloft (150mg) from Celexa, they cut me off Celexa cold turkey and ramped me up to 150mg within four weeks. It was hell. Side effects: sleepiness, anxiety, depression, jaw clenching, dizziness, panic attacks, diarrhea, loss of appetite. Side effects hung on for at least the first four weeks. 

I'm about three months in now and feel much better. 90% normal."
