depression
"This has been a life changer for me. I guess I never realized how depressed I actually was until I started on Zoloft. I'd been fighting it for years, forcing myself to get up and get by each day, but getting worse and worse (avoiding people, having problems talking, having horrible insomnia).

Within a week of being on Zoloft I noticed a major difference. I actually feel optimistic about life for the first time in as long as I can remember. My relationships with my wife, family, friends, and coworkers have all improved dramatically. In short, I'm no longer depressed. 

I had some side effects over the first few days (restless legs, night sweats, a zonked out 'zombie' feeling) but they passed quickly."
