i take lamictal (400 mg/day) and have no memory loss. before lamictal, i couldn't remember anything anyway because my mind raced so much. there are a number of mood stabilizers available (depakote, risperdal, tegratol, seroquel, trileptal, etc.) many can cause weight gain and other side effects. keeping a pad of sticky notes nearby might help. before lamictal, i always had to write things down. best wishes.
