I dozed a lot. I was unsteady at first, but once I got going it was easier than I expected and actually walked down two halls and back to my room. The walking was encouraged, even required to a point. It helps stimulate your circulation, which aids healing and also builds confidence, which helps make you feel better which is a sort of self-fulfilling thing. It is generally agreed that a good attitude will help you through times of less than ideal circumstances, so getting out and about, as long as it wasn't overdone was encouraged.
Activity combined with plenty of rest is usually the best way to heal.
The next day I tried to go to class. At the hospital where I received my transplant, part of your recovery includes attending a week of daily classes which teach you about your transplant, medications, how to tell if something is wrong as well as how to try and keep yourself healthy. The first day, however, I was too uncomfortable and tired and had to leave the class and return to my room. I slept well that afternoon. The next day I managed to last all the way through the class, I felt their classes were very important.
