Actually I joked to a friend last week that going for the treatments is my only break! My days seem to get pretty busy. So it's relaxing to just sit there and veg out.
My mother is there with me, and she goes to the snack bar in another part of the building and gets us a roll or something to snack on, and there is free coffee...
The doctor will even get it for you! How cool is that.
He seems to get miffed if you don't want any!
