When I had my vEEG - I was permitted to bring my own
clothing as long as you can unbutton from the front.

One of the hardest thing is trying to be FORCED to stay
awake if your Epileptologist / Neurologist orders it. It's
boring, boring, boring.

However - they will NOT permit you out of bed if you have
electrodes that have been inserted in your jaw or head.
PERIOD.

As for the cables - you will be free to roam about, but
there is a way to walk around and keeping you from being
twisted is to coil the cable first as if you were holding a
microphone and walk with you - releasing as you go and
vice versa.

If there's nothing good on tv - you can always watch your
Digital EEG - it can be pretty interesting watching the XLEvent.
