Maybe it's the Lamictal and the Welbutrin together...synergy of them.

I took Welbutrin for years and got two college degrees 3.97GPA and climbed in my carreer with no memory problems.

Like lolagrace said maybe it has something to do with the Lamictal. It messed my memory up quite a bit....but I got it back.

I know everyone's different so my experience is too.
