Take this for what it's worth, it's just my opinion....
You should see a doctor. If your seizure pattern is currently changing for the worse (increasing frequency) and you don't do anything to control it, it could get very, very bad.
My wife's seizure pattern has changed a *lot* over the last 10 years (frequency, type, severity, etc). She too used to only have tonic-clonic seizures about once every two weeks - always when she first woke up in the morning. But it can change. You cannot rely on past history as proof that you will never have one in the middle of the day (or while driving for that matter).
