I've been on Zoloft 50mg for 4 months due to post partum depression. I was told to take one tablet before bed and when I did I couldn't sleep, my mind would race. So then I would take it first thing in the morning but would feel sluggish and lazy all day. I definetly gained weight from it and hope I can lose it now that I've been off it cold turkey for 7 days. However I've had extreme dizziness almost to the point of where I've fallen since I stopped taking it. Also while I was on it I had no sexual desire at all and couldn't reach climax. At first I felt the pill really helped, maybe it was more of a placebo or to low of a dose. However now that I've stopped I feel better and much more mentally motivated. It could possibly be that I feel better because I don't have post partum depression anymore, but I do now I won't be using it anymore.
