I have seizures and chronic migraines with difficulty sleeping on a regular basis. I do suffer from depression due to the seizures beginning at age 48 with no prior history. I have had migraines since age 25 with increase in frequency and intensity in recent years. There has been no known etiology for the seizures (e.q.- no history or family history). My neurologist has prescribed this drug to me but I have noticed that some days the drowsiness is more pronounced than others. I wish to learn all I can about this drug.
