I've been on Lamictal for over a year for borderline personality disorder. It's worked great for me & I've never had any issues with it before. Recently I've been experiencing mild vertigo & a sense of haziness. I went to a GP who did some tests (EKG, hemoglobin count, etc) which all came back normal. He seemed to think that, despite the fact that I've been on Lamictal for as long as I have with no issues, the medication was probably causing the vertigo. Has anyone else had this problem? I haven't increased my dosage or anything, it just started out of nowhere.
