Hello John and June.
Welcome to this merry band of individuals, not a place any of us want to be, but here we are.
Sorry to hear that June has kidney and sickness problems, I'm sure that they will soon sort things out.
I was 67 when diagnosed, went through the Myeloma XI drug trial, eventually had a stem cell transplant ( this February ) and am on the remission road, had a two month break from all clinics and am currently not on any drugs or treatment, except for a monthly penidronate infusion. Just as Tom says it is doable.
You know it's a sharp learning curve and you learn more as you go along, don't let it stress you out, June needs you!
Good luck to you both, let us know how it goes.
Regards
Tony F
