Why did you stop the Lithium? Or did you not? It is the best for mood swings over the track record the others have, such as Depakote, Tegratol, etc. I take Lamictal, I did take Lithium, my brother has for 33+ years, I took it for a year, I hated the other stuff, made me fat and real tired, being that I am Bipolar-II (mild) I get more depressive than manic so the pdoc said to give Lamictal a try, and I didn't take antiedepressants after, they "pooped" out so this was the best choice, but if I ever need Lithium again I'll jump at it.
You can't play with dosages you need to follow the pdocs recomendations and stick to them for best results.
Just my 2 cents.
Please take care
