Hi Amy,
I have Temporal Lobe seizures, mine aren't triggered by lighting or anything I have identified.
The following link has some information you may find useful. They discuss prodrome and pre-Ictal phases of seizures, attributing prodromes up to 24 hours in advance of the seizure. There's also a questionnaire you may find useful.
www.sciencedirect.com/science/article/pii/S105913110800232XOther sites list prodromes up to days before a seizure. Although I could find nothing specific about
delayed seizures, it seems implicit that if the prodrome can occur 24hrs or more before - that a trigger may set the process in motion at that early time.
If you operate cars or machinery, and have an uncontrolled seizure disorder, and can harm yourself or others if it occurs while you're driving or operating a machine. Despite not having insurance, you may be able to find a clinic at a local hospital that can arrange for the necessary testing and examinations.
