A little while ago I began to get panic attacks that would wake me up around 3 am every night. They were due to stress at work. I saw a psychiatrist and she prescribed Zoloft. Since then my anxiety has gone away and work is no longer stressful. However, I continue to wake up every night between 2 and 4 am for last few months. No panic attacks. It’s like a habit that no matter how relaxed I am going to bed, I will always wake up. Has anyone experienced this and is there anything I can do?
