Raspberry, I am just now reading your post. I have taken both lorazepam and clonazepam. How much clonazepam were you taking? When you say that you are taking 1 mg of lorazepam, do you mean 1 mg per day in one dose? Is this an every day dose or as needed?

A lot of the difficulty in switching from clonazepam to lorazepam depends on if you were/are taking the drugs regularly.

I can't address the issue of whether the lower seroquel dose is causing anxiety, but clonazepam is so much longer-acting than lorazepam, that I would think switching from one to the other would be likely to cause some disturbance in your mood (either sedation or anxiety) until the clonazepam gets completely out of your body and your body adjusts to the lorazepam.
