I am bipolar 1 and have ADD. After my bipolar symptoms were managed, my psychiatrist added Vyvanse. Vyvanse has been a good med for focus and organizing my thoughts. It was like adding a piece of the puzzle that was missing. I improved a lot once it was included. Because I take it with mood stabilizers, I haven't experiencing any problems with mania from it thus far. I've been taking it for 2 years. Of course, people react to all medications differently. This is my experience with it.
