Absolutely!!!!
The period after stem cell collection, with no drugs was great for me. I felt more or less like myself again. I went off to Kent, and a family party in London and last week camping in Wales, plus gardening, cycling, seeing friends.
Use the time to do all the things you enjoy and make you feel good and healthy. Eat good enjoyable food, get exercise and see lovely people. That way you'll be in good condition for the transplant.
Have fun!
