I found that taking a Tylenol or something similar shortly prior to treatment helped a lot because the back of my head got sore from the hard table. I did not have arms and legs restrained but promised to stay very still, which was easy because I generally dozed. And yes, by the second week, the mask which feels very tight at first, begins to loosen. You will do just fine, Cave! Oh, one more thing. It was quite chilly where I was treated and the attendants will happily cover you with blankets if you ask.
