How do you spend your time in the linear accelerator?

I had three initial days of waiting on the table for my bladder to fill for one reason or another. On the third day I got as close to a panic attack as I've ever been with an irrational fear of my legs moving.

I've improved a lot since then and I haven't made the bladder mistake again. Today I was out the door 10 minutes past my time slot (okay, okay, they were running 5 minutes early today).

If you know the last verse of Hotel California you might appreciate how I passed my time in the machine yesterday...

Blue skies on the ceiling, pelvis on the screen
And she said, "We are all just prisoners here of our own machine"
And from the rad techs' chamber, the photons are released
We don’t stab you with those steely knives, because that just won't kill the beast
Midway through September, I’ll be running for the door
I have to find the passage back to the place I was before
"Relax," said the desk man, "We are programmed to receive
You can hit the bell before you go, cos we want to see you leave"
