Hi there ~
It might take some time for the effect of the medication lamotrigene to set in and you might need an increased dose at some point in time depending on your response to medication. Optimum dosage would be necessary to make you epilepsy
free. I hope you have any other co morbid medical condition under control and are seeing a neuropsychiatrist for your problems. I hope this helps.
Take care and have a lovely day!
