My experience in taking Zoloft for the last month and a half has been largely side-effect free. However, I feel like I am constantly in a fog. It takes me until about 3:00 in the afternoon before I have any motivation to do anything. I have been taking 100mg because of post-partum depression. My anger and violent thoughts have mostly gone away, but I just feel so tired and listless all the time. I was first prescribed Neevo, a prenatal vitamin that seems to have some anti-depressant effects. It didn't help, but I read that it can help process normal anti-depressant medication, so I started taking it with the Sertraline (Zoloft generic). Since then, I have felt a little better, but I still lay around all day trying to motivate myself to play with my baby or clean the house.
