Quetiapine, like Olanzapine is an atypical antipsychotic which is used for the management of Bipolar (which I have), insomnia, anxiety disorders along with a varitey of other disorders. I take 800mg which is quite a high dose. Although I haven't experienced weight gain with it, other people have. I think it's just a case of finding the right medication for you, a bit like trial and error.

I do take other medication including Mirtazapine, Zopiclone, Lamotrigine and Diazepam.

I think it would be a good idea to talk to your doctor about the options available which may be more suitable for you.
