A valium and a blindfold help me with the claustrophobia . . . but imagine laying in that tube, of course flat on your back, when that position causes bowel urgency! By the time they get enough padding for me so this problem is lessened, I can't move! I tell them each time I have an MRI done that there is every chance I will need to escape the tube, and quickly . . . or the repercussions could be dreadful. I don't look forward to them for this reason.
