"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."
