I felt like a zombie on Depakote, too. I agree it would be a good idea to talk to your pdoc about how you're feeling and your temptation to quit meds completely. There are lots of other alternatives that can help control your moods without leaving you in limbo. I've had really good results with both Seroquel and Abilify, and many people are happy with Lamictal, to mention just a few. If you go off meds completely, you risk falling into a serious mood episode.
