bipolar disorde
"I found this medication helpful with reducing hypomanic symptoms - mainly I took it to control episodes of violent rage which it did. It gave me tachycardia so I had to discontinue. 
My PROBLEM with this medicine is that it has changed my body permanently (so far - it's been 3 yrs). I was one of those people who could eat whatever I wanted, exercise, not exercise - I never gained weight. Now I'm carrying an extra 10 kgs which I am NOT happy about. I can't get rid of it.
