Lamictal I have been taking Lamictal 150 mgs for about 2 years to prevent Basilar migraines. This medicine saved my life. I was having these scary migraines where I would have stroke like symptoms (loss of speech, vision and confusion) two or three times a week. My Dr. started me on a very low dose and stopped titrating me up when I hit a therapeutic level . I have night sweats, some nightmares and some anxiety at times but I'm willing to get over it because I don't have the migraines.
