Oh, boy do I get headaches. Always have. Right after a seizure. My Dr. used to give me hydrocodone but, since they were moved from a schedule 2 drug to a 1, he won't give them to me anymore. What he did give me in it's place is Rizatriptan 5mg. It works pretty good. Hope this helps.

My daughter has headaches before and after a seizure, she says Tylenol works

After one first comes too and every where is noisey and overwhelming, and feeling sick etc, yes, thencomes a really bad head as if your head is under a weight. Yes, I should imagine this is like a hang over

I sometimes can't sleep because it's that bad

I have the same thing as of yet the only thing I have found that helps is sleeping. But it could take any where from 1 hour to 12 hours depending on how bad my seizure was. Hope this helps.
