If anything i feel energized afterwards, but that might be from sitting for so long. I can't wait to walk around. The most difficult part is not going to the toilet for 2-3 hours. (I can go during the second half of the treatment if I wheel a drip.) So the whole process takes about 5 hours at the hospital.
Half way through the course of treatment I have lost weight (fluid) and other physical signs are good. We are still waiting for my blood tests to indicate a turn for the better.
