I was on 150 mg Zoloft for about 7 years, and then decided to quit taking it cold turkey...that was NOT smart. I definitely experienced side effects in my mood, and actually lost a year of time which I can't remember a dang thing about that time. (e.g. there are pictures with me in them but I have no clue where I was or what I was doing)

But, Zoloft didn't give me any weird side effects when I was taking it properly and was quite helpful. My advice from my experience is: if u start taking the meds and then the time comes when you think it is time to stop taking them, do it under a doctor's care, not on your own. but like Chris said, no two people seem to experience exactly the same thing...good luck!
