i was wondering how long it takes for Zoloft to work/kick in??? i started by taking a half of a 25mg for a week then took the 25mg for a week, and now im on 50mg for a week. so far i have the shakes, cant sleep, no appetite and im still very sad. i was hoping that it would have started to make me feel better by now. can anyone give me any feedback, i appreciate it so much!
