I have had series of spells. But that was a long time ago before I had my brain surgery

Yes . I use to have bad cluster seizures. I would going to a seizure and come out.. moments later I’d go into another seizure come out. I’ve had times where it’s happened many times I was so exhausted., I fell asleep into the next day

Okay, so you are asking about one after another. Yes, I have. It is rather common. However, I believe it can become a medical issue if you pass the one minute mark. The jury is still out on if that is cumulative. Or are you inquiring about having various different types in a row? Examples: absense, tonic clonic, focal. They are very scary when it’s one after another. Even worse when no one is around.

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
