Hi Andy
Like the others, I am gutted thst you can't find a donner match. However, I'm glad the drugs are working. The donner transplants don't sound like a walk in the park, so maybe, with your battered bone marrow, going other routes may not be such a bad thing, IF they can find a combination that whacks the blasted MM into touch.
Very best wishes to you and Steph.
