It depends what type of seizure you've experienced and how severe. If possible, make sure you're not alone, and make sure that someone knows you're epileptic. You may experience another seizure.

You can try numerous tricks. Take a standard multi-vitamin to replace what you lost to the seizure. Drink plenty of water. A tad of salt will replace the sodium and chloride (chlorine ion).

Mostly you need sleep so your brain can regenerate the Adenosine Tri-phosphate and neuro-transmitters lost to the seizure. Also, Pedialyte will help restore electrolytes.

Your doctor may consider a shot of vitamin B-6.

There isn't much that will seriously decrease recovery time. Sleep is about the best thing you can do.

My partner has grand mal and nearly always hurts himself.usually the head.he never remembers having them.he sleeps a lot after.
He tries to hide it but I'm used to looking for the signs now.
He works.it is hard to watch but I try and make him comfortable.
He gets really stroppy after and does some strange things like trying to get cupboards off the wall. He gets agitated when I try and keep him safe.he used to just sit and go asleep but now he walks rather staggers about..

STRESS!!! is a HUGE trigger so i try and NOT be around it. When i feel the ups and downs, usually which i compare to the feeling of being on a roller coaster, i sit down and drink something cold. If someone is around and aware they will stay with me and rub me soft. If the seizure comes anyway, i just have to take it and recover. Sometimes depending on the severity and when and where depends on what i will be able to do. During my grand mal seizure which I've been known to have in my sleep and alone, i usually wake up from a long but short walk through my apartment, ending in a tragic trip and fall. Bruised and bloody. Did i REALLY start my exercise plan today??? if so, man what a workout!!! my muscles!!! my body!!! my goodness!!! im SO tense and what just happened?!?! i can't really remember until i see my tongue. MAN!! this was a bad experience... i would wish on no one!!! i then dust myself off and get myself together and clean up the mess. call my family so they are aware and then a wet cloth and try to sleep💤💤💤

When I was having so many of them I was raising my kids. So I took a brain boost formula and ate healthier food. I took brief naps if needed while they were resting.
But as they got older and into school. I'd play soothing music and have cold drinks. I also wrote a lot of things out of how I was feeling before and after them or if I felt like I lost some time during the day without realizing it.
I don't have them like I used to. but on nights I can't sleep I'll take sleep aids if needed. As I know poor sleep can contribute to my recovery from any of my issues. Find something to focus on like reading, music, nature or fresh air. thinking about it won't help. I know that from experience

Sleep and cannabis is all I can say as am tottaly wiped out for the next 2days wether I have them in my sleep or awake and anyone will know if I have one when am awake and aware as I'll just stare off in to space at one point and my eyes will glaze over and just mumble or not talk to you at all and over I'll sleep for the next 8 hours. And the next day is just as bad. Thankfully they have subsided some but the medication is no better.
