I read your original posting yesterday and felt compelled to respond today, just in case. Do you have a natural gas appliances in your house? If you do, please consider a natural gas leak detector (different from a carbon monoxide detector). I know that your doctor diagnosed it as seizures and this is often how people with natural gas poisoning are diagnosed. I am harping on this only because this is my experience this week. Today, I have no working oven as it is taken apart and there are pieces everywhere while the cause of the leak is found. But no more bad headaches, dizziness, etc.
