I have been on Lamictal for a week now. My body reacts not so well to anything new so I have to start on half of the 25mg for a few days to introduce it. I didn't have any side effects but I took a 25mg today at 7am and just now at 530pm I'm feeling nauseous... is this normal? I'm working up to 100mg and I'm really anxious about it. Any tips would be nice.
