seeking,
Welcome to SR, glad you found us.
Although my son is not an IV user, he uses anything available...and we , (Mr. Moose and I)have tried various solutions to bring him to sobriety.
Nothing has worked, we were just spinning our wheels and making ourselves sicker.
You can lead a horse to water........
Please try Alanon mtgs. They have helped me remain somewhat sane through this LONG journey of my TWO sons addictive lives.
