Hi, Steve.
Congratulations on the donation.
I think your notebook is a great idea. Expanding on Fr. Pat's advice about BP, you might like to keep a log of your physical symptoms and milestones, to keep track of how quickly you and your body return to normal in various ways. Also, on the "psycho-social" level, how you feel about the whole process. This could even include stuff about how your friends and co-workers reacted, family dynamics, etc. All this might be interesting to the staff at the transplant center, so they have a better, more realistic basis for telling people what to expect. Maybe you could also keep a list of suggestions, both for donors/donor candidates and the transplant center. This could include a "Things I wish I'd known" section.
And, naturally, the LDO list would be a perfect audience as you track your progress. Good luck!
Be well, Snoopy
