Hi cris! Welcome to CWE.

As you can see, we're a friendly group. My best piece of advice would be for your son to start keeping a journal. Have him write down everything he eats and drinks (how much and when), how many hours of sleep he gets, any stress he's under, if he has any seizures, how long they lasted, and what he was doing right before they hit. It will help in trying to figure out what is causing the seizures. Also, if he drinks energy drinks, tea, or coffee in large quantities, he should cut back. I notice you put a limit on the video games. Good idea. Also, your son should probably quit drinking alcohol if he does.
Also, if he happens to have a seizure do NOT put anything in his mouth. I know it might look like he's swallowing his tongue, but he's not. If you put anything hard in his mouth like spoons or sticks, he runs a risk of shattering his teeth or biting you (which your husband already found out). People have lost fingers trying to put things in people's mouths. How to help him? Move anything that he might hit away from him, and if you can, roll him onto his side. He might bite his tongue, but at least he won't choke on his own saliva. I have grand mals. For me, the very last thing to return is speech. I can see people around me, then my hearing comes back, and the last thing to come back is my speech. The paramedics here will ask questions to see how far I am in getting back to normal. Things like, "what's your name, what year is it, do you know what day today is"... Stuff like that. If you see your son have a seizure, time it. See how long it's lasting.
As for depakote, I was on that for a long time. For me, it worked great.

The only major side effects I had was weight gain. So don't be surprised if your son packs on some pounds.
Feel free to ask questions, vent in the padded room (epilepsy can be frustrating), or just chime in .

Also, check out the Epilepsy 101 thread under my signature. It's got some great basic information. And finally, don't be surprised if your son's EEG comes back normal....alot of us here have epilepsy and totally normal EEG's.

Anyway, I hope this helped. And remember, you're not alone.
