I had been seizure free for over 3.5 years using lamictal until this past week when I had two. I thought the first was from sleep deprivation but I can't figure out why the second one happened. The ER doc called my doc and they said I could go up 100 mgs a day on my dosage, now I am dizzy. Has anyone else had a similar experience with lamictal? Or has anyone gone a long period of time and started to have seizures again - without explanation?
