depression
"I suffered from inherited depression (chemical imbalance). My family doctor put me and my mother on it at the same time. We both were nauseous and had headaches for the first 2 weeks, the subsided. Then we went up a dose after a month to 100 mg and had the same side affects again but then went away. Now we are both happy-go-lucky. Zoloft made me normal again. Which I had forgotten what normal was years ago. Saved my marriage and my life as well. I recommend taking it at night though. "
