bipolar disorde
"I am taking this medicine to treat Bipolar Disorder Type 1 and I have never had a side effect.  I have been taking it for about 5 years in conjunction with Gabapentin.  About six years ago I started having dual episodes, which were new to me as I had only experienced mania or depression.  After a few stays in the hospital and being introduced to Lamictal, I have not had a dual episode, or any episode at all. Lamictal has also stopped 96% of the paranoia feeling that has never gone away."
