Why 6 - 7 pm seizures only

I have recently been diagnosed with absence seizures. I am using epilim 1000 mg in the am and 1000 mg in the pm. However every two to three weeks for the past 4 months i have been experiencing the seizure but only during the hours of 6 - 7 at night, i repeat only during this time. Why is this so? and How can i prevent these seizures from happening at all.

Are you having just one seizure at this time? Are you having many in a row, but only in between 6 and 7? What are you doing at this times?

In the last 3 months I have had 3 seizures, The fisrt one was at 12 and the other 2 was at 9 pm. I take 125gm of Lamictal twice a day. Not sure why is it happenening around the sametime in the evening?
