24 hour EEG

Got a phone call today from the epilepsy center... there has been a cancellation and now Kalle can have his 24 hour EEG on monday. Aahhh! So we have to be in Heeze (near Eindhoven) on monday morning, 8:30. One of us will be with Kalle all the time, until the next morning.
It scares the hell out of us. Kalle had some really weird days. Now we're afraid that his EEG will be really, really bad, worse than the last one. Do we really want to know?? And what about the consequences? We don't want more drugs, more side effects. But on the other hand...we don't want more seizures either.
