Marle,
I'm so sorry you are facing this situation and sorry that it looks as though Megan is doing some more "research" out there. I'm praying that she will get to a bottom quickly so she can bounce back up.
In the meantime, keep those recovery tools that you share so well with others close by your side. It never gets easier for us moms watching our kids reject recovery. But we know there is always hope. And I'm praying the recovery she has REALLY messes up her drinking and/or using.
Will be praying for y'all daily.
Hugs,
Hangin' In
