I am wondering if anyone taking Lamictal notices if it causes brain fog. I increased my dose to 100 mg today and have felt foggy all afternoon/evening. I took it at 8 am so I wonder if the fog could instead be caused by Lamictal wearing off in the afternoon? I'm confused b/c when I'm depressed I have brain fog. My head felt clearer on a higher dose of my antidepressant so my doctor told me to increase it again. I really don't want to take anything that makes me foggy. What have your experiences been with this?
