I'm on 200 mg of Lamictal. It's neither activating nor sedating. It is the only drug I can take to even out depressive episodes. Although severe mania is a far bigger problem for me, my psychiatrist is a master at managing it. Unfortunately there isn't a single antidepressant I can take that doesn't make me wildly manic. Lamictal is all I have to manage depressions. Oh, and light therapy, very carefully dosed.
