Yea that sounds alot like me, I have begged, pleaded, talked, listened, cried, pretty much everything you described.
If I hadn't found this site I am not sure where I would be right now. I have taken some great advice from this board and from the book I have been reading.
This is still all pretty fresh for me, but I am trying to fight off the backslides and become stronger.
Yea I have a brother that is very similar to your Doc. Pretty much had the same conversation with him.
