Hi there,
Seroquel has helped me for my OCD and panic attacks. It basically completely got rid of my panic attacks, actually, and I had been having them almost every day. The only issue was that it made me too tired, so I switched to the Seroquel XR (extended release) and it's working quite well. I'm now on 600mg of the Seroquel XR. Other side effects for me are occasional blurred vision, and increased appetite.
Best of luck to you in searching for the right med for you.

Talking to your psychiatrist about your concerns can help as well.
