I wish I could help. I've never taken Zoloft, though.

Like Inny, I can relate to the dizziness. I had a severe case of treatment-resistant Benign Paroxysmal Positional Vertigo from 2000-2003, so I was extremely dizzy, off-balance, had blurred vision and basically felt seasick all the time. I couldn't do much of anything (lost my job, etc.) while I had it. I'm a whole lot better now and just get occasional dizzy spells -- particularly from motion or when I get a bad cold.

There is a very common virus that causes labyrinthitis. It tends to go around in the spring and it can make you very dizzy. You should go talk to your doctor. The dizziness might be an effect of withdrawing from Zoloft or it could be something else like viral labyrinthitis (which usually lasts a week or 2). Good luck. I hope you feel better soon. Being dizzy all the time is no fun. I've been there.
