i have been on Zoloft five years. at first it seemed to provide relief from depression. I began to experience gastro problems. No one even suggested that it was the zoloft. I have gained 39 lbs, and no energy. I took myself of this drug by decreasing the dosage over two weeks. not long enough. Now I have electrical jollts going through my head, very foggy brain, anxiety, etc. will the wieight gain go away? am i losing my mind? please comment.
