How long do your DC usually sleep after a tonic clonic seizure? DS normally sleeps for about 2 hours but after this morning’s seizure it’s coming up for 5 hours and he’s still asleep. He is muttering ‘go away please’ when I go in there so is conscious, but I’ve never known him to sleep for so long. He was much groggier than usual after the seizure - he’s normally wobbly and slurry but this time needed support to walk the few steps to his bed. Should I be worried?
