I've been taking 500 mg/day (250 mg/ 2x daily) of Lamictal and 1800 mg/day (600 mg/ 3x daily) of Neurontin for about 4 years. It's reduced my seizures, but I've noticed severe memory loss, clumsiness, confusion, and sleep disturbances. Is anyone else on this combination, and if you are, have you noticed these same effects? The memory loss and confusion are so bad that I'm afraid to try to work in a stressful environment again! Is this just an exceptionally high dose, or is this average?
