I'd like to add, I found Lithobid to work great during a rough, agitated state I had been in with my Bipolar - II, it is a great med for those who tend to have manic episodes, more than depressive ones.
I being the type to lean towards more depression, the switch to Lamictal was the best thing,
Well, like they say not all people respond the same.

PS
Nice to see you again, Cam
