Welcome MacIrish,
Welcome to Sober Recovery.
I don't know much about Methadone, but to me, it's a positive sign for her to be discussing alternative methods to beat her pill addiction.
I do know that she has to help herself. There is nothing you can say or do to make her stop using, it's all up to her.
What are you doing for you?
Attending any Alanon, or Naranon meetings?
They're great for support, and focusing on you.
keep posting, we're all here for you,
