Lamotrigine
"I have Bipolar 2. I was diagnosed in 2009 but had suspicions long beforehand.  So was put on Prozac, Abilify. While I notice Prozac helping, especially when I don't have any and I begin having withdrawal, I've found that Lamictal really does the job! It's very subtle,  maybe because I'm on a very low dosage. Yet, I notice it. I'm more calmer. Not calm completely,  just calMER."
