Lamotrigine
"This medicine has been amazingly helpful. After being misdiagnosed with depression I began taking this once my bipolar symptoms were diagnosed correctly. For those of you who may not think the drug works, I wonder if your doctor is doing a blood test to determine if your dosage meets the therapeutic level. Also, I learned the hard way that birth control pills totally negate the effect of Lamictal. It took a while to straighten that one out. Thanks to all for writing in."
