When I was out there I had family threaten me, & beg me to quit, the pleas of my children and my wife meant absolutely nothing, it was not until I was ready to quit that I put myself into detox because I did not want to die that I was able to even begin to recover.
If you give him a penny until he is ready he will spend it on drugs, give him a house full of furniture and he will sell or hock it all to get a fix.
You can do nothing for him, everything you do for him will just enable him to not hit his bottom.
He will OD here just as quickly, maybe quicker since he will have all kinds of good stuff to sell for drugs.
For your own sake go to Alanon, learn that there is nothing you can do for him, you need to live your life and not let him pull you down the toilet with him. As long as you hold onto him the less chance he will have of hitting bottom and beginning recovery.
