You're going to find that being sympathetic and supporting your brother is only going to take you so far, in the end it becomes another enabling factor. At some point you're going to have to give him some tough love, kick him in the ass and tell him to make a choice. Honestly, that could be the rock bottom that he needs, when his family says "we're done"
If he can't stand the meetings, then just quit cold turkey. If he can't do that then go to the meetings. If he can't do either, then he's made the choice that his addiction is more important than his life and family. There's only one end result of that choice and it's not good.
that's all I have from the nsmb life choices forum
Listen to Dave. He just gave you all the information you need. It took my family to walk away from me to make me get help.
The 'higher power' thing is a way to help a lot of addicts draw on something other then themselves to get through the tough times. Addicts have low self esteem and very little faith in their own ability to recover, this 'higher power' allows the separation needed.
