I am currently taking 150mg Zoloft for the past six months. Before that I was taking 150 of Effexor. I suffer from anxiety and depression. My family doctors doesn't seem to think it the Zoloft that keeps awake. Mt insomnia has gotten worse since June but I personally feel better. Should I come off the Zoloft and try something else. I realize I do have to take something for obsessive thinking, depression and anxiety.
