Lamotrigine
"It seems to be helping, but still some depression remains.  I have Bipolar Type 1, so I have struggled with mania, hypomania, mixed mood, and depression.  I do notice I'm more "even," which is what the medicine intends to do.  I take a combination of meds, so it could be difficult to tell which medicine is doing what.  All I know is that I have no side effects, which is good, because I requested a mood stabilizer that will not make me gain weight.  Overall, I'm satisfied with the way things are going (thank goodness, because Bipolar could be hell)."
