Carbamazepine
"I do feel that this medication works, regular blood work to check levels in the blood are crucial.   I have been diagnosed with bipolar disorder for 16 years and have been on this medication since the year 2000.   It worked better back then, I do have an appointment with a psychiatrist to go over the mediaction as I do not feel that it is working as good as it used to.  Perhaps my body has become immune to it."
