This seems like an AWFULLY high dose. My grown son is calling me saying he is getting lots of double vision and, when he has double vision, he can barely walk. He had every neurological test in the book, including CAT scans and MRIs. They are normal. I looked up side effects of Lamictal and it says double vision and lack of coordination. Son is getting so bad they won't let him go to work for now. He is also on...are you ready...8 mgs. of Xanax CR a day. I told him to call his doctor and insist that he wants his medications lowered. Anyone have experience with Lamictal? Is the dose a really high dose? I know I am medication sensitive to the extreme. Son could be too (he is my biological son). Help? Smallmom? Where are you?
