I started on 25 mg Zoloft for one week then titrated to 50 and have been on 50 for 9 days. My anxiety is worse, especially in the morning. I also have slight insomnia. I have clonopin for breakthrough anxiety but I'm worried about becoming dependent on it. How long typically does it take for anxiety to subside? Also, I've had a nervous stomachache for the past two days. Is this common! Does this mean the Zoloft might not be working for me?
