Hi jpnme,
I am the mother of two adult sons,ages 26, and 32, who are addicts.
My heart goes out to you, I know the emotions, and turmoil you may be feeling.
I would suggest backing off a bit, and letting him take over the responsiblity of his recovery.
There's a bunch of parents, and other loved ones who post on the Naranon forum.
Hope to see you over there.
Welcome to Sober Recvery.
Prayers for you, and your son.
P.S. Have you attended any nar-anon, or al-anon meetings?
They are a Godsend!
Hugs,
