Was forced to cold turkey from sertraline (zoloft / lustral), how long until I feel better?

A week or ten days. If you are having discontinuation symptoms from stopping zoloft (sertraline), (sertraline) they should go away by ten days after your last dose. These might include feeling dizzy like the room is spinning, feeling achy, hearing swishing noises when you move your head. If you are experiencing some other symptoms, it may not be from stopping zoloft (sertraline), (sertraline) it may be underlying problems that zoloft (sertraline) was helping with, that came back.
