Starting to go unconscious during seizures, gaps in memory

Last week I had a few seizures and I could remember having seizures but I cannot remember being in the ambulance. I had some more 2 days after and I remember having the seizures at a hospital car park and being taken via trolley to the hospital you to the entrance but I can't remember being taken to the bed I was on.

I was out drinking a few days ago. I already had a few seizures earlier that day before I drank but I felt better and wanted to go out.

Basically I drank a lot and went to get a taxi home and had seizures. I lost my glasses somehow and according to the a&e letter I was unconscious. I don't remember anything between first collapsing and not long after arriving at the hospital. All my blood tests were normal and they did a CT scan of my head and that was normal, got fluids and was sent home after some sleep.

My memory goes bad after some seizures but I never lose consciousness usually. I can remember seizing after some time after the post ictal phase but on these occasions there's parts of what happened I have no memory of and I was not given rescue medication on any of these instances.
