re under the supervision of your doctor. Many of these types of meds need to be tapered and
Zoloft is one of them.
When you resumed taking it and realized you had mistakenly taken 200mg, you probably should have called your doctor or pharmacist for advise, and since you are still feeling not so great, I'd call someone . Being the week-end, you probably won't reach your doctor, so try your local pharmacist.
