bipolar disorde
"For years I had been (mis)treated for clinical unipolar. I went through many SSRIs, but each one "hit the wall" - had only limited effect on the deepest depression, and none as a maintenance drug. Changed pyschs. She suggested an off-label use of Lamotrigene. Within a couple of weeks I felt so much better! We scaled  back (and eliminated) Effexor SSRI. I continued to get better. She moved away, so I had to find another psychiatrist - or psych nurse. The new psych nurse did an interview, and said I was being treated for the wrong disease. I felt better because Lamotrigene was working on my bi-polar! 5 years later, I'm still doing well - mood swings moderated, deep depression less deep and less frequent."
