I am bipolar - obsessive personality-post traumatic stress disorder....I am on Depakote and Seraquel ..... My psychologist has agreed with me recently that I may need a med change, I fight with the seraquel eating habbits every day whick drives me crazy because weigh gain is one of my obsessions.....Lithium was mentioned, what side effects may I have from that? I am so worried about new side effects, but know i do in fact need the change.
