bipolar disorde
"I have Bipolar 2 & for years was misdiagnosed as being depressed. Fluoxetine made me hypomanic and when unmedicated I suffered prolonged episodes of depression. My most recent depressive episode had lasted 9 months & my levels of anger, aggression, irrational thoughts & behaviour and feelings of utter despair were very frightening. 
I began taking lamotrogine at 12.5mg dose and slowly titrated up over 10 weeks to 100mg. Even at the 50mg dose my mood was not lifting so reluctantly my psychiatrist introduced venlafaxine which I now take at 150mg. The lamotrogine has stopped my racing thoughts, incessant & excitable talking, my irritability & aggressive outbursts. I have the calm peace of mind & control of my emotions I never thought I would."
