I've been on lamictal for about three months now "300mg"...I also take 80mg strattera.
I was taking Cymbalta before switching over to Lamictal, the sexual side effects of Cymbalta were too severe (I was impotent)...Dr. decided to try Lamictal in hopes of regaining my drive, so far there is has been "little" improvement...maybe I need more than three months?
Anyway haven gone through withdraw of Cymbalta and slowly easing into a therapeutic level Lamictal has been total hell.
Good luck
