Before I got my Depakote, I would sometime experience multiple episodes which I discovered were called 'series'. Sometimes they lasted all day. Other times they lasted for days. My personal record is four days straight. When I told a friend about what I experienced, she said, "You must be exhausted."
I have had series of spells. But that was a long time ago before I had my brain surgery
My seizures have much the same as yours, my doc calls them clusters. Before meds, I would have as many as 15 a day and then a couple the following day and repeat about 4 or 5 days later. After 7 years of changing meds my event have been reduced to about 4-5 seizures a day every week to 10 days.
So your clusters are more intense but I think maybe similar to others. Keep working on getting the right meds mix and if it says the same check into VNS or RNS.
Good luck
