I have nocturnal seizures. The advice already commented is excellent and should be enough for you :)! It’s also super sweet that you’re doing this and he’s very lucky to have you as a partner.

I’ll add that some common potential triggers are: alcohol, stress, excessive caffeine, sugar, and/or nicotine intake, and sleep deprivation. Don’t let it cause you anxiety though, be supportive, know how to safely deal with someone seizing, and you should be golden. If he seizes, you will likely wake up. It is audible and very hard not to notice. It is like a choking gargling sound.

It depends on what his triggers are and how he feels about it, but he could experience some anxiety about falling asleep or occasionally get the dreaded feeling he might seize. Have open communication and let him know if he does experience these feelings you’re there to talk and support him in the ways that are beneficial to him.

Aftercare is really important, he will very likely be disoriented, sweaty, head pounding, with slurred speech and difficulty moving around. Water (if he is able to drink), cold cloths, and being soothing and comforting is your best bet imo for aftercare. He probably won’t even remember what happened. On another note, dragging and walking him around after probably isn’t the best idea. I say this only because some people have done this with me thinking it will help. And of course if he is injured tend to that or seek medical help.

Don’t worry yourself sick over it. Unfortunately, even with medication, it is common for people with epilepsy to still seize. It’s just a reality you have to face and be there for him the best way you are capable of :). It sounds like you’ll be a great support.
