Good luck tomorrow. I am sure that you will sail through the process. I do recommend that you take plenty of clean PJs though.
I had my SCT 19 months ago. The first week was toughish – diarrhea, sickness, loss of appetite, hair loss – all the usual stuff. However I had no mouth ulcers or infections. From then on things looked up. I was in hospital for just 2 weeks and then was sent home.
I was quite weak at first, but with two dog, I worked hard to get out and about with them. Starting slowly using my wife's mobility scooter, within 4-6 months I was walking the dogs 4-6 miles a day.
So good luck. I am sure that after the first week, things will get better day by day. Chase the nurses to give you your blood counts every morning. Seeing your WBC count climbing day by day is so encouring and you'll know that you'll soon be home.:-)
Cheers, Roger
