I finished taking my zoloft exactly 9 months after I started taking it, my doc told me to stay on it for 9 months and she said " as long as you have no 'episodes' you can stop taking it. So I did because I hate taking pills that deal with your brain,especially the side effects it can have.
I was lucky and I had no episodes, I slowly weaned myself off it and had a little bit of a weird feeling especially when I turned my head to look behind me, I took it as a withdrawl symptom because after a month it was gone.

So good for your for not neeeded it anymore!
