There is an epileptologist at Rush who had seizures himself. See if you can get to see him.

1, If the szs are getting worse, why are you still taking the meds?
2, I did have a problem when sleeping on the left side. If I felt a sz coming I would roll over and sometimes stop it,
3 I don't have szs anymore (after 36 years) because I had the surgery, Ask your doc about surgery
