depression
"Zoloft has been a complete hell for two months and a half. I've tried to up the dose to 75 as I was taking 50. With no results, but it made me dizzy to the point I couldn't drive, nauseous and exhausted. Also, this medication has increased my social phobia. A complete hell. To those thinking on taking Zoloft, please consider other options. I've never felt so bad in my entire life. 
Now changing to Prozac."
