Politicians are due to cast their vote on a controversial and fundamental change to the organ donation system in Wales.
Martyn Griffiths, 36, from Aberdare, South Wales, is waiting for a heart, lung and kidney transplant.
A kidney he received from his mother a few years ago is failing.
He said the proposed changes would help him, adding: "There are days when I get fed up and don't want to go to dialysis".
